Question
3. A playground has a small merry-go-round with radius 1.00 m. It's moment of inertia is 125 kgm2. A
small child with mass 35.0 kg runs at a velocity of 2.50 m/s along a path tangent to the outer rim of the
stationary merry-go-round and jumps on. Calculate (a) the magnitude of the angular momentum of the
child about the axis of rotation of the merry-go-round, and (b) the angular speed of the combined
merry-go-round plus child after the child jumped on. You may assume the child is a point mass.
