Question 1. A ball is initially moving at 8 m/s up a ramp. The acceleration of the ball is -2 m/s/s down the ramp. What is the balls velocity after 7 seconds? (frame of reference + is up the ramp)

Question 2. If a ball is released from rest from a tall building and lands in 5.60 seconds, how tall is the building? Use g as 9.80 m/s/s
