Abowler throws a bowling ball of radius r = 11 cm along a lane. the ball slides on the lane with initial speed vcom,0 = 6.0 m/s and initial angular speed ω0 = 0. the coefficient of kinetic friction between the ball and the lane is 0.35. the kinetic frictional force f with arrowk acting on the ball causes a linear acceleration of the ball while producing a torque that causes an angular acceleration of the ball. when speed vcom has decreased enough and angular speed ω has increased enough, the ball stops sliding and then rolls smoothly.(a) what then isvinterms ofω? (b) during the sliding, what are the ball’s translational and angularacceleration? (c) how far does the ball slide?

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?
