A coin is tossed upward from an initial height of 7 m above the ground, with an initial speed of 7.4 m/s m/s.
The magnitude of the gravitational acceleration g = 9.8 m/s2
Take the point of release to be y0 = 0. Choose UPWARD as positive y direction.
Pay attention to the signs of position, velocity and acceleration.

A ball is dropped from a height 24 m above the ground at t=0.0. Each time it bounces from the ground, its rebound speed is 60% of its impact speed. At the instant the first ball hits the ground, a second ball is released from the same place. Take g = 9.8 m/s2. At what height above the ground will they collide? (Take the ground as y=0.0 m)
