To define the time of flight equation, we should split the formulas into two cases:

100 mph

1. Launching projectile from the ground (initial height = 0)
2. t = 2 * V₀ * sin(α) / g.
3. Launching projectile from some height (so initial height > 0)
4. t = [V₀ * sin(α) + √((V₀ * sin(α))² + 2 * g * h)] / g.

770 m.

A cannon is fired towards the edge of a cliff. It is found that if the cannon is fired at exactly 38 degrees above horizontal then the cannonball will just barely touch the edge of the cliff, which is 313 meters away.

Given the initial speed of the cannonball and the angle at which it was shot, can you determine how far it will travel? So there you have it — now you can figure out the range of the cannon given the speed of the cannonball and the angle at which it was shot. Your range is 75 kilometers, or nearly 47 miles.

about 1.1 meters

How to use the free fall formula: an example

1. Determine the gravitational acceleration.
2. Decide whether the object has an initial velocity.
3. Choose how long the object is falling.
4. Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + gt = 0 + 9.80665 * 8 = 78.45 m/s .

if you throw a rock off that, right at the bottom, right before it hits the ground, it will have a velocity of negative 9.9 meters per second. So negative 9.9 meters per second.

Which ball will be traveling faster when it hits the ground? -Ball 1 and ball 2 will be traveling equally fast when they hit the ground.

When you drop a ball (or anything) it falls down. Gravity causes everything to fall at the same speed. This is why balls that weigh different amounts hit the ground at the same time. Gravity is the force acting in a downwards direction, but air resistance acts in an upwards direction.

In other words, if two objects are the same size but one is heavier, the heavier one has greater density than the lighter object. Therefore, when both objects are dropped from the same height and at the same time, the heavier object should hit the ground before the lighter one.

Heaver objects fall faster. If you drop a heavy and light object together, the heavy one will get to the ground first.

A Marble, A Piano And Banana The idea is that everything falls at the same rate, no matter what its mass is. The bowling ball has a greater mass, so there’s more stuff for gravity to act on. In that sense, gravity is pulling on it more. But it still doesn’t fall any faster.

Spoiler: the answer is that they will all fall at the exact same rate. Though some objects, like feathers, seem to fall slower because of air resistance.

If no air resistance is present, the rate of descent depends only on how far the object has fallen, no matter how heavy the object is. This means that two objects will reach the ground at the same time if they are dropped simultaneously from the same height. In air, a feather and a ball do not fall at the same rate.

You might think this would cause the coin to fall faster. But because of the coin’s greater mass, it’s also much harder to accelerate the coin than the feather—50 times harder, in fact! The two effects exactly cancel out, and the two objects therefore fall with the same acceleration.

The gravitational acceleration g decreases with the square of the distance from the center of the earth. So all objects, regardless of size or shape or weight, free fall with the same acceleration. In a vacuum, a beach ball falls at the same rate as an airliner.

23. Which falls down faster in a vacuum – a feather, a wooden ball or a steel ball ? All will fall down at the same speed in a vaccum because there will be no air resistance. ANSWER : : All will fall down at the same speed in a vaccum because there will be no air resistance.

Because Earth gives everything the exact same acceleration, objects with different masses will still hit the ground at the same time if they are dropped from the same height. The less massive the object is, the more the force of air resistance slows the object down as it falls.

The simplest answer is: no, an object’s weight usually will not change its falling speed. For example, you can test this by dropping a bowling ball and a basketball from the same height at the same time–they should fall at the same speed and land at the same time.

The laws of gravity dictate that a bowling ball will always drop faster than a feather.

heavy objects will have a higher terminal velocity than light objects. It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed.) Therefore, heavy objects will fall faster in air than light objects.

While even short drops can be lethal, people have survived horrendous falls. In very high falls, bodies can reach terminal velocity, the speed at which air resistance becomes so high it cancels out the acceleration due to gravity. …

Does a falling body accelerate? Why? A Yes, because the gravity is a force that causes it to move faster.

one second

If he falls for three seconds, the distance he has fallen is solved using the formula of distance = 1/2 * g * t^2. Bt filling in the values of g and t, the equation becomes distance = 1/2 * 9.8 m/s^2 * (3 s)^2. After 3 seconds the body has fallen 44.1 meters.

Heaver objects fall faster. If you drop a heavy and light object together, the heavy one will get to the ground first. This is trick question. I remember in physics that everything falls the same.

The force of gravity is the weight of the body. Hence an object with greater mass feels greater force than the other one. So even if the slope is same for both objects, a massive object moves faster through the slope than a less mass object.

To go fast, I needed to minimize the surface area of skin and suit making contact with the slide. Basic speed-chuting position involves crossing your ankles, tensing your core, and arching your back so that there are only three points of contact with the slide: the shoulder blades and a single heel.

Heavier bikes and riders are faster downhill because they experience a higher force from gravity, but have relatively the same wind resistance as a lighter rider and bike. The only variable is mass, so the heavier mass will have greater force to overcome air resistance.

134 km/hr

The velocity at which the accelerating force and the velocity-dependent drag force are at equilibrium is known as the terminal velocity. In vacuum since there is no drag force, the terminal velocity does not exist.

around 53 m/s

Terminal velocity is acquired by a body in presence of external constant force if and only if it experiences an additional retarding force which varies directly proportion to instantaneous velocity. In vacuum, there is no retarding force, so it will not acquire terminal velocity.

Since the drag force is going up much more quickly than the constant acceleration, you eventually reach a perfect balance between the force of gravity and the drag force of whatever you’re moving through. Outside the Earth’s atmosphere, though, there’s no terminal velocity.

Terminal velocity is the fastest that an object will ever fall, no matter what height it is dropped from. Squirrels (unlike most other mammals) can survive impacts at their terminal velocity. Which means no matter what height you drop a squirrel from, it will probably survive.
