Thank t = 0s t = 1s t = 2s t = 3s 6. Snapshots are taken of a rotating football at four moments in time as shown above. The ball goes through less than one full revolution between each snapshot. What graph of angular displacement vs. time best represents the rotational motion of the ball? OV OV OV ev 7. A basketball player spins a basketball of radius 12 cm on her finger at an initial rate of 20. rad/s. A patch on the equator of the ball experiences a tangential acceleration of magnitude 0.24 m/s as the ball slows due to friction with the player's finger. What is the angular speed of the ball after 3.0 seconds? 1 cm ( 20rad /5 ) (0.zum / 12 ) ( 3. 05 ) A) 19 rad/s B) 14 rad/s C) 12 rad/s $1 1.1 rad/s 8. A string is attached to a fixed point on an icy surface and tied at the other end to a 160-gram puck. The puck travels across the ice, without friction, on a circular path at constant speed. The string is 25 cm long and is under 6.6 N of tension. What is the linear speed of the puck? 6.6 ( lol ) .. B ) 13 m / s C) 10 m/s D) 3.2 m/s 9. The diagram shows three forces acting at the same location on the rim of a wheel. All three forces have the same magnitude. Which force axis exerts the largest torque on the wheel? D) All three exert the same torque. Page 5 of 10
