A Lazy Susan (turning tabletop) has radius 0.750 m.  An apple is placed at the edge of the turning table. A child turns the tabletop from rest to an angular speed of 5.00 rev/min in 3.00 s.  What is the value of the apple’s centripetal acceleration at the 3.00 second in m/s2? Enter units as “m/s^2”

A girl of 50.0-kg skating at 10 m/s crashes into another girl of mass 35.0-kg moving in the same direction at 8.0 m/s.  Assuming the impact lasts 0.15 s, after which they move together, how fast (in units of m/s)  are they moving immediately after crashing?
