A ball is dropped (from rest) from a window and hits the ground with a speed of 5.5m/s. If the ball were dropped from double the height, what would be its speed (in m/s) when it hits the ground?

If there were no air resistance, a penny dropped from the top of a skyscraper would reach the ground 8.65 s later. To the nearest integer, what would the penny’s speed in m/s be right as it reaches the ground if it was dropped from rest?

A ball is thrown vertically upwards at 9.5 m/s. For its complete trip (up and back down to the starting position), its average velocity in m/s is?

A long jumper leaves the ground at an angle of 29 degrees and lands 8.2 meters away. With what speed did he jump? Please answer in m/s

Each time a ball bounces, it reaches 85% of the height reached on the previous bounce. Initially, it is dropped from a height of 5 meters. What is the total distance traveled by the ball after 7 jumps?

A ball is thrown off the top of a 30m cliff with horizontal velocity of 10 m/s. How far from the base of the cliff does the ball land? Express answer in meters.

A soccer ball starts from rest and accelerates with an acceleration of 0.385 m/s2 while moving down a 8.50 m long inclined plane. When it reaches the bottom, the ball rolls up another plane, where, after moving 14.75 m, it comes to rest. (a) What is the speed of the ball at the bottom of the first plane (in m/s)? (Round your answer to at least two decimal places.) m/s (b) How long does it take to roll down the first plane (in s)? (c) What is the magnitude of the acceleration along the second plane (in m/s?)? m/s2 (d) What is the ball's speed 8.20 m along the second plane (in m/s)? m/s (e) What If? You change the angles of the two inclines in such a manner that the new acceleration down the first incline is a, new down = 2a initiel down and up the second incline is a, new un x initial up, What is the ball's speed 8.20 m up the second plane (in m/s)? 2 m/s

Julie drives 112 mi to Grandmother's house. On the way to Grandmother's house, Julie drives half the distance at 41 mph and half the distance at 60 mph. On her return trip, she drives half the time at 41 mph and half the time at 60 mph. What is her average speed on the return trip?

A worker at the top of a 425-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 ball of 5kg is shot vertically upward with 19.6m/s.  What is the maximum height it can reach (in meter)?
