A bat strikes a 0.145-kgkg baseball. Just before impact, the ball is traveling horizontally to the right at 47.0 m/sm/s ; when it leaves the bat, the ball is traveling to the left at an angle of 29.0 ββ above horizontal with a speed of 59.0 m/sm/s . The ball and bat are in contact for 1.71 msms . Part A Find the horizontal and vertical components of the average force on the ball. Let +x+x be to the right and +y+y be upward Express your answers using three significant figures separated by a comma.
