A6.0 kg disk traveling at 9.0 m/s strikes a 7.0 kg stick of length 5.0 m that is lying flat on nearly frictionless ice as shown in the overhead view in the figure below. The disk strikes at the endpoint of the stick, at a distance r = 2.5 m from the stick's center. Suppose that the collision is perfectly inelastic so that the disk adheres to the stick at the endpoint at which it strikes. The moment of inertia...

A golf ball (50 g) hit by a club is accelerated from rest to 50 m/s in 2.50 ms. What are the magnitudes of the impulse delivered to the ball and the average force acting on the ball? Impulse = Average Force = A disk of radius 10.0 cm spins about an axis through its center at a constant 5.0 rad/s. What is the linear velocity, centripetal and tangential accelerations of a point on its rim? linear velocity = centripetal...

Page 13 9. A 49.8-kg athlete running at 4.54 m/s suddenly jumps onto a stationary playground merry-go-round at a distance 1.45 m from the axis of rotation of the merry-go-round. She is traveling tangential to the edge of the merry-go-round just before jumping on. The moment of inertia about its axis of rotation is 625 kg m2 and very little friction at its rotation axis. What is the angular speed of the merry-go-round just after she has jumped onto it?...
