Question:
1. A students wants to investigate the motion of a ball by conducting two different experiment, as shown in Figure 1 and Figure 2 above. In Experiments 1, the students release a ball from rest and uses a slow-motion camera to film the ball as it falls to the ground. Using video analysis, the students is able to plot the ball’s horizontal position x and vertical position y as a function of time t. In Experiment 2, the student horizontally rolls the same ball’s horizontal position x and vertical position y as a function of time t starting from the instant the ball leaves the table. The graphs from each experiment are shown above along with each graph’s best fit curve line.
2. Suppose the Experiment 1 and Experiment 2 are conducted at the same time: one student drops the ball rest at the same instant that a second student horizontally rolls and identical off the table. After both balls have traveled half their vertical distance to the floor, what is the acceleration of the center of mass of two-ball system relative to Earth?
a. Greater than g
b. Equal to g
c. Less than g, but not zero
d. Zero
