AP Physics TBT-Circular Motion Name: Arm Length = 0.7m 9 = 450 Mr. H holds an incline (calculator base) at arm's length with a 45 degree angle as shown. He carefully rotates at just the right rate such that a ping pong ball (0.06kg) on the incline does not roll or slide up or down. A) Sketch a free-body diagram illustrating all forces acting on the ball at this point B) Determine the speed of the ping pong ball
