A child sits on a merry-go-round at a distance of 3.0 m from its axis of rotation. The coefficient of static friction between the child and the surface of the merry-go-round is 0.6. Find the largest angular velocity (in rpm) the merry-go-round can have before the child starts to slide outward. Your solution must show a free-body diagram of the child.

    5. A 3.0 m diameter merry-go-round (mass 200 kg) is spinning at 10 rpm. A child of 30.0 kg runs tangent to the merry-go-round at 2.0 m/s, in the opposite direction that it is turning, and jumps onto the outer edge. Calculate the merry-go-round's angular velocity, immediately after the child jumps on.

    A 40.0-kg child running at 3.00 m/s suddenly jumps onto a stationary playground merry-go-round at a distance 1.50 m from the axis of rotation of the merry-go-round. The child 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 600 kg ? m2 and very little friction at its rotation axis. What is the angular speed of the merry-go-round just after the child has jumped onto it?...

    A brave child decides to grab on to an already spinning merry-go-round. The child is initially at rest and has a mass of 26.5 kg. The child grabs and clings to a bar that is 1.45 m from the center of the merry-go-round, causing the angular velocity of the merry-go-round to abruptly drop from 55.0 rpm to 19.0 rpm. What is the moment of inertia of the merry-go-round with respect to its central axis?

    A brave child decides to grab on to an already spinning merry-go-round. The child is initially at rest and has a mass of 34.5 kg. The child grabs and clings to a bar that is 1.70 m from the center of the merry-go-round, causing the angular velocity of the merry-go-round to abruptly drop from 51.0 rpm to 17.0 rpm. What is the moment of inertia of the merry-go-round with respect to its central axis?

    A merry-go-round is spinning at 3.00 revolutions per minute. A crate is placed on it at a distance 2.00 m from the axis of rotation. If the coefficient of static friction between the crate and the surface of the merry-go-round is 0.30, will the crate stay on the merry-go-round, or will it slip and fall over the side?
