A .145 kg baseball moves horizontally towards the batter with a speed of 40 m/s. The bat exerts an average force on the ball of 7000N at an angle of 11 degrees above the horizontal. The ball is in contact with the bat for 1.3 ms. Determine the velocity of the ball just after its struck.

A baseball approaches home plate at a speed of 48.0 m/s, movinghorizontally just before being hit by a bat. The batter hits apop-up such that after hitting the bat, the baseball is moving at56.0 m/s straight up. The ball has a mass of 145 g and is incontact with the bat for 2.10 ms. What is the average vector forcethe ball exerts on the bat during their interaction? (Let thepositive x direction be from the mound towards home plate. Let thepositive y direction be up.)




A pitcher throws a 0.14-kg baseball toward the batter so that it crosses home plate horizontally and has a speed of 42 m/s just before it makes contact with the hat. The batter then hits the ball straight back at the pitcher with a speed of 48 m/s. Assume the ball travels along the same line leaving the bat as it followed before contacting the bat. 

(a) What is the magnitude of the impulse delivered by the bat to the baseball? 

(b) If the ball is in contact with the bat for 0.005 s, what is the magnitude of the average force exerted by the bat on the ball? 

(c) How does your answer to part (b) compare to the weight of the ball? 

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 55.0 m/s, and it leaves the bat traveling to the left at an angle of 30 degrees above horizontal with a speed of 60.0 m/s. The ball and bat are in contact for 1.65 ms.

a.) Find the horizontal component of the average force on the ball. Take the x-direction to be positive to the right. Use two significant figures.

b.) Find the vertical component of the average force on the ball.
Express your answer using two significant figures.
