A pendulum strikes a billiard ball m= 165g, causing the billiard ball to slide across a table as shown in the data below. The radius of the billiard ball is r= 2.62cm

@ 1. The angular position and angular velocity were measured for the ball and the data are shown in the table below. Angular Angular position Velocity A pendulum strikes a billiard ball m = 165 g, causing the billiard ball to slide across a table as shown in the data below. The radius of the billiard ball is T = 2.62 cm. 2. Use the data table and graph above to determine a, the angular acceleration of the billiard ball. B I U XX= E Vx PDF EB Score: 0/2 3. Determine the net torque experienced by the billiard ball. B I U XX= EEEE @ Vx a PDF Score: 0/2@ 4. Using the center of mass of the ball as the axis of rotation, what force provides the external torque acting on the billiard ball? @ The gravitational force of the earth The normal force of the track on the ball. The frictional force of the track on the ball The contact force of the pendulum on the billiard ball. @ 5. Explain your reasoning for (4). BIxix'EEEEEEOOBFEE @ 6. A student makes the following observation: I measured made a position vs. time graph for the ball and it looks linear. This means that the ball has a constant velocity and the net force acting on the ball is zero, which means the frictional force must be negligible in this situation.

If the ball were replaced with a hollow sphere of the same mass and radius, and this experiment were repeated, how would the distance the hollow ball travels before it begins pure rolling motion. The hollow sphere would slide for a larger distance than L before pure rolling. The hollow sphere would slide for a smaller distance than L before pure rolling. The hollow sphere would slide for a the same distance as L before pure rolling. ($3 10. Explain your answer to (9). B I U X X' E E VX & PDF Score: 0/2 11. Draw two extended free body diagrams for the billiard ball for each of the following situations. a. When the ball is sliding and rolling. b. When the ball is experiencing pure rolling motion.
