Question

A ball is slowing down as it rolls on grass in a playground. It's angular acceleration is -1.8rad/s² and its linear acceleration is -0.045m/s².

a) What is the ball's diameter in centimetres?

b) when the ball's speed is 0.14m/s, what is its angular velocity?

c) If the ball's initial angular velocity was 9.0 rad/s, how long does it take to come to rest?

A bowler throws a bowling ball of radius R = 11 cm down a lane. The ball slides on the lane with initial speed vcom,0 = 11.0 m/s and initial angular speed ω0 = 0. The coefficient of kinetic friction between the ball and the lane is 0.22. The kinetic frictional force fk 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...
