In physics lab you want to observe objects moving under constant acceleration. At the same instant, you drop a golf ball from a height of 2.0 m above the ground and throw a golf ball directly upward with an initial velocity of +3.0 m/s from a height of 2.0 m.
a. Draw a motion diagram for each of the golf balls.
b. What is the difference in the time at which they hit the ground?

1. A car starts from rest and travels for 8.0 s with a uniform acceleration of +1.8 m/s2. The driver then applies the brakes, causing a uniform acceleration of −1.5 m/s2. If the brakes are applied for 2.0 s, determine each of the following. (a) How fast is the car going at the end of the braking period? (m/s) (b) How far has the car gone? (m) 2. A ball is hit with a paddle, causing it to travel straight...
