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
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!

A pitcher throws a 0.145 kg baseball at 40.19 m/s at the catcher (who is standing still). It takes the catcher 0.07 seconds to stop the baseball after catching it. What was average force required to catch 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...

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 batter swings at a baseball (mass 0.145 kg) that is moving horizontally toward him at a speed of 40.0 m/s. He hits a line drive with the ball moving away from him horizontally at 50.0 m/s just after it leaves the bat. Part A If the bat and ball are in contact for 8.00 ms, what is the average force that the bat applies to the ball? Express your answer with the appropriate units.

8. A 3. A pitcher claims he can throw a 0.145-kg baseball with! as much momentum as a 3.00-g bullet moving with a speed of 1.50 X 10° m/s. (a) What must the baseball's speed be if the pitcher's claim is valid? (b) Which has greater kinetic energy, the ball or the bullet? en bone break A railroad car of mass 2.00 X 10' kg maving collides and couples with two coupled to each of the same mans as the...

A baseball has a mass of 0.145 kg and a radius of 3.70 cm. In a baseball game, a pitcher throws the ball with a substantial spin so that it moves with an angular speed of 35.0 rad/s and a linear speed of 37.0 m/s. Assuming the baseball to be a uniform solid sphere, determine the rotational and translational kinetic energies of the ball in joules. Correct Sig Figures. KErotational? KEtranslational?

8. A 0.145 kg baseball pitched at 35.0 m/s is hit on a horizontal line drive straight back at the pitcher at 50 m/s. If the contact time between the bat and the ball is 0.020 seconds, then: a. calculate the change in momentum of the ball. b. calculate the average force between the bat and the ball during contact.

A 0.145-kg baseball pitched at 39.0 m/s is hit on a horizontal line drive straight back toward the pitcher at 51.5 m/s . If the contact time between bat and ball is 3.50×10−3 s , calculate the average force between the ball and bat during contact.
8. A 3. A pitcher claims he can throw a 0.145-kg baseball with! as much momentum as a 3.00-g bullet moving with a speed of 1.50 X 10° m/s. (a) What must the baseball's speed be if the pitcher's claim is valid?
