Homework Help: Physics

Posted by Leanna on Thursday, February 3, 2011 at 10:06pm.

So for each of the statements we have to write true or rewrite the part in Caps to make the sentence true. I'm only stuck on a couple.

1. On a position-time graph, the average velocity equals the run MULTIPLIED by the rise.

2. A child drops a ball. The instantaneous velocity of the ball as the child lets go is ZERO.

3. A child drops a ball. The instantaneous acceleration of the ball as the child lets go is ZERO.

4. A toy rocket is launched vertically upward. When the rocket reaches its highest point, its velocity is at ITS MAXIMUM.

I think 1 is divided, 2 is true, 3 is true or 9.80m/s^2, and I don't know about 4
