the mass of a baseball is about 140 g. the pitcher pitches the ball at 90 mph. assume the batter hits the ball and there is a home run. if the work done by the bat on the ball is Wnc=70 j, estimate the speed of the baseball after the hit when it is 25.0 m (82 ft) above the point at which the ball is hit. HINT: Should the speed of the ball after the hit be higher or...
Now assume that the pitcher throws a 0.145 kg baseball parallel to the ground with a speed of 32 m/s in the +x direction. The batter then hits the ball so it goes directly back to the pitcher along the same straight line. What is the ball's velocity just after leaving the bat if the bat applies an impulse of -8.4 N*s to the baseball? I just cant figure out how to do this problem. Please help!
