Question

A bat strikes a 0.145- baseball. Just before impact, the ball is traveling horizontally to the right at 50.0 , and it leaves the bat traveling to the left at an angle of 40 above horizontal with a speed of 55.0 . The ball and bat are in contact for 1.85 . Part A Find the horizontal component of the average force on the ball. Take the x-direction to be positive to the right Express your answer using two significant figures. = SubmitMy AnswersGive Up Part B Find the vertical component of the average force on the ball.

Explanation / Answer

v1 is initial velocity horizontal v2h is final velocity horizontal at is acceleration-time velocity change v1-at =-v2h (v1+v2h)/t =a 40 +65cos40/.00185 =a a= -48537 m/s/s F=ma F = (0.145)(-48537) Fhorizontal average = 7037 N to the left v1=0 v2v =65sin40 v=at a=v/t F=ma F=mv/t F = (0.145)(65sin40)/(0.00185) Fvertical average = 3275 N upward
