A 45.0 kg child runs up to a merry-go-round at a speed of 7.5 m/s. The merry-go-round can be appoximated as a solid cylinder with a mass of 215 kg and a radius of 3.5 m. If the child jumps onto the merry-go-round and lands a distance of 1.0 m from the edge, determine the angular velocity of the merry-go-round just after the collision. The child stays on the merry-go-round and it stops spinning after 35.0 s. Determine the magnitude of the frictional torque that stops the merry-go-round

Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.
