E t . 18-B+ | | Emphasis Heading i L Normal | Subtitle Paragraph Styles Pre-Lab Questions 1. What is the acceleration of a ball that is vertically tossed up when it reaches its maximum height? When the ball hits its maximum height the ball's acceleration is 0 because the ball at a stall till it starts going downwards. If you drop a ball, and then one second later drop a ball identical in mass, size and shape, what happens to the distance between them as they fall? 2. The distance from when you drop the balls a second apart will stay the same because of t fact that they are the same ball, so they will stay going the same speed, unless another for acts upon a ball. 3. What does a positive and negative slope represent for a velocity versus time graph Positive and negative slops are the reciprocal of each other. As the velocity goes up ov time it is positive and as the velocity decreases over time its negative. So when talking about velocity versus time graph, positive and negative slopes are showing how fast something is going over a period of time or how slow something is going over a perlod time

Explanation / Answer

1. The motion of the ball can considered as the freely falling body the acceleration of the ball the remains constant. g = 9.8 m/s2.

2. the equations of the motion are no where related to the mass , size and shape of the ball

the time difference between the two balls remains constant as they travel downwards. and the the balls velocity maintained same during their journey
