In a softball game, a 0.200 kg softball traveling at 12.0 m/s at an angle of 50.00 below the horizontal is hit by a batter.  Just after the hit, the ball is traveling at 45.0 m/s at an angle of 35.00 above the horizontal.  Video shows the collision time between the bat and ball was 25.0 ms.  Determine the magnitude of the force exerted on the ball by the bat.

An ice skater has a moment of inertia of 5.0 kgm2 when her arms are outstretched. At this time she is spinning at 3.0 revolutions per second (rps). If she pulls in her arms and decreases her moment of inertia to 2.0 kgm2, how fast will she be spinning?
