A worker at the top of a 366-m-tall television transmitting tower accidentally drops a heavy tool. If air resistance is negligible, how fast (in m/s) is the tool going just before it hits the ground?

A rock is thrown (at an unknown angle) with a speed of 15.5 m/s from the top of a 32.9 m high cliff. What is the impact speed of the rock when it reaches the ground?

So this is the problem I am trying to figure out: A boy tosses a coin straight up to 2.2 m. Suppose the height when the coin leaves his hand is 1.3 m. What was the initial speed of the coin when it left his hand?

A roller-coaster goes over a 12 m tall hill then approaches a 30 m hill. What is the minimum velocity the roller-coaster would need when going over the 12 m hill to make it to the top of the 30 m hill?   Question 4 options:   254.8 m/s   Not enough information to answer   18.78 m/s   15.96 m/s

A 15 kg ball is thrown straight upward with a speed of 22 m/s. What is the maximum height the ball reaches?

Julie, mass 36kg, has invented a new ride called the Human Launcher. It is basically a platform that springs people straight up into the air. She is testing it, standing on a bathroom scale on the platform. As the platform springs 10.0m upward from rest, Julie notices the scale reads 600.0N. Once it reaches ground level, the platform suddenly stops, but Julie doesn't, and is launched up into the air. What is the maximum height above the ground that Julie will reach? (the ride was deemed unsafe and cancelled) *= nut 10.0m ground

A ball is thrown downward from the top of a building with an initial speed of 25 m/s. It strikes the ground after 2.0 s. How high is the building, assuming negligible air resistance?

A worker at the top of a 390-m-tall television transmitting tower in North Dakota accidentally drops a heavy tool. If air resistance is negligible, how fast (in m/s) is the tool going just before it hits the ground?

A ball is dropped (from rest) from a window and hits the ground with a speed of 7.0m/s. If the ball were dropped from double the height, what would be its speed (in m/s) when it hits the ground?   Your Answer:

Dr. Liu is learning how to juggle. He tosses a tennis ball (probably bad choice since it is so bouncy) up at 2.5 m/s at a height 1.5 m above the floor and attempts to use the other hand to catch the falling ball. The ball hit the floor at his feet. How long was Dr. Liu's tennis ball in the air (between tossing and landing)? Ignore air drag. He should probably practice tossing his juggling ball at the same height and same speed before attempting to juggle. Hint: You can set the final position to be zero.
