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 lower Write your principles and equations.

    a baseball pitcher throws a baseball (145 grams) towards the batter at a speed of 35 m/s. the batter swings her bat (940 grams) with an unknown speed towards the ball. the bat hits the ball, and the ball goes flying back toward the pitcher at a higher speed. if the ball's speed (not velocity) increases by about 20% and the bat's speed decreases by about 50%, what was the initial speed of the bat before it hit the ball?...

    A pitcher throws a 0.140 kg baseball, and it approaches the bat at a speed of 35.0 m/s. The bat does Wnc = 75.0 J of work on the ball in hitting it. Ignoring air resistance, determine the speed of the ball after the ball leaves the bat and is 25.0 m above the point of impact.(Answer in m/s)

    S2. (5 pts) A baseball pitcher of mass 80 kg at rest pitches a baseball of mass 0.15 kg at 50 m s-1 towards home plate. Throwing that ball, the pitcher recoils in the directly opposite direction which is towards second base. What is the speed at which the pitcher is pushed towards second base?

  • A baseball pitcher throws a 157 g baseball at a velocity of 31 m/s towards home...

    A baseball pitcher throws a 157 g baseball at a velocity of 31 m/s towards home plate. The batter hits the ball, and the velocity of the ball coming off the bat is 52 m/s in the opposite direction of the velocity of the pitch. The bat is in contact with the ball for 0.003 seconds. What is the magnitude in Newtons of the average force applied to the ball?

    A baseball pitcher throws a 141 g baseball at a velocity of 33 m/s towards home plate. The batter hits the ball, and the velocity of the ball coming off the bat is 54 m/s in the opposite direction of the velocity of the pitch. The bat is in contact with the ball for 0.003 seconds. What is the magnitude in Newtons of the average force applied to the ball?

    A baseball pitcher throws a 146 g baseball at a velocity of 25 m/s towards home plate. The batter hits the ball, and the velocity of the ball coming off the bat is 50 m/s in the opposite direction of the velocity of the pitch. The bat is in contact with the ball for 0.004 seconds. What is the magnitude in Newtons of the average force applied to the ball?

    A pitcher throws a 0.143-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 bat. The batter then hits the ball straight back at the pitcher with a speed of 51 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...

    A pitcher throws a 0.138-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 bat. The batter then hits the ball straight back at the pitcher with a speed of 46 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...

    1. In Major League Baseball, a typical fastball is pitched at a speed of about 90 mph, or 40 m/s. The batter can perform the remarkable task of completely reversing the direction of this ball and sending it back at about 105 mph, or 47 m/s. Doing this at just the right millisecond to get the ball to go where the batter wants it to go is such an amazing feat that a Yale physicist once jokingly declared that hitting...
