What is the velocity of a stone thrown from a building?

A stone was thrown from the rooftop of a 20-m building at 30 m/s at an angle of 45 deg. How long will it take the stone to hit the ground? The time of flight of the stone is the time it has risen from the top of the 20 m high building at an initial velocity of 30 m/s until dymax plus the time the stone fell from dymax to the ground.

How long does it take a stone to hit the ground?

It will take the stone 5.12 s from release until it hits the ground. If the stone is thrown vertically downward with a velocity of 15 m/s from the edge of the building, calculate the velocity after 3.0s.

What is the time of flight of the stone?

The time of flight of the stone is the time it has risen from the top of the 20 m high building at an initial velocity of 30 m/s until dymax plus the time the stone fell from dymax to the ground. It will take the stone 5.12 s from release until it hits the ground.

Velocity is 42.7 m/s at ground impact. 5.77 seconds total time in the air. A stone is thrown vertically upwards from the top of a building 50 m tall with an initial velocity of 20.0 m/s. If the stone just misses the edge of the roof on its return.

What happens when a stone is thrown vertically up from the tower?

A stone is thrown vertically up from the tower of height 25m with a speed of 20m/s time taken to reach the ground? The stone will reach the ground in 5 seconds after being thrown upwards from the tower. It will reach some height where its final velocity will become zero,

How long does it take a stone to reach the ground?

The stone will reach the ground in 5 seconds after being thrown upwards from the tower. It will reach some height where its final velocity will become zero, a = − g = − 10ms−2 —-negative as it is going in direction against the gravitational pull.

What is the maximum height of the stone at T=20/9?

With an initial upward speed of 20 m/s and a downward acceleration of 9.81 m/s², the stone will reach zero velocity and therefore its maximum height at t = 20/9.81 = 2.04 seconds. Since the rise and fall of the stone are symmetrical, the time that the stone takes to return to its starting point is 2×2.04 seconds = 4.08 seconds.
