Q. A skier with a mass of 61 kg starts from rest and skis down an icy (frictionless) slope that has a length of 70-m at an angle of 32° regarding the horizontal. At the bottom of the slope, the path levels out and become horizontal, the snow becomes less icy, and the skier begins to slow down, coming to rest in a distance of 160.00 m along the horizontal path.

Q. A circular saw blade completes 1200 revolutions in 40 rm s while coasting to a stop after being turned off. Assume constant deceleration, what are (a) the angular deceleration and (b) the initial angular speed?
