Question
1. a baseball pitch throws a fastball to the catcher. assume the ball starts from rest in the pitcher's hand and that the ball is brought to rest in the catcher's mitt. also assume the ball loses no velocity while in flight.A. how will the balls change in momentum from the pitcher's throw compare to the change in momentum while being caught?
would the momentum of the thrower be larger.. or the catcher will be larger?
B. which player exerts a larger impulse on the ball? pitcher or the catcher
C. which player exerts a larger force on the ball? the pitcher or the catcher? and why
2.consider a ball falling to the ground.
a. why is momentum not conserved from the perspective of the ball? explain
b. define a system for which the momentum of the ball falling to the ground is conserved
Explanation / Answer
1. Both will exert same impulse 1. The catcher takes less time than the thrower to provide the same amount of impulse while catching so catcher exerts more force. 2.there's a gravitational force acting on the ball which changes the momentum of the ball If we consider earth and the ball as a system then the momentum is conserved as the ball also exerts equal and opposite force on the earth
