- Example:
- A ball is thrown straight up in the air with initial velocity of 9.8 m/s.
- Ignoring air friction, answer the following questions.
-
- (1) What is its velocity at its peak?
-
- At its peak, the ball is changing from a positive
- velocity (away from the ground) to a negative velocity
- (toward the ground). Therefore, at the peak the
- velocity is 0.
