1. A burglar attempts to drag a 111 kg metal safe across a polished wood floor Assume that the coefficient of static friction is 0.4, the coefficient of kinetic friction is 0.3, and that the burglar can apply a pushing force of 532 N on the metal safe. What is the acceleration of the metal safe across floor? 

 2.  A 22.0 kg child is riding a playground merry-go-round that is rotating at 40.0 rev/min. What centripetal force must she exert to stay on if she is 0.889 m from its center?
