Acceleration and velocity are two distinct concepts.

At the top of a cliff 98 m high, Raoul throws a rock upward with a velocity of 29m/s. How much later should he drop a second rock from rest so both rocks arrive simultaneously at the bottom of the cliff?

A) If a ball moving at 5m/s receives constant acceleration of 1m/s2 at the same direction, how long will it take the ball to reach 10m/s? 1 s 3 s 5 s 7 s B) If a ball's horizontal initial velocity is 20m/s and the flight time is 5 seconds, what is the ball's horizontal distance? 4 m 20 m 50 m 100 m

An object is dropped from rest and hits the ground with an impact velocity of 7 m/s (downwards). How much time was it in the air?

A ball is thrown straight up with an initial speed of 12 m/s. How long does it take to reach its highest point?
