Acatcher catches a 145 g baseball traveling horizontally at 32.0 m/s. part apart complete how large an impulse does the ball give to the catcher? express your answer in kilogram-meters per second. pp = 4.64 kg⋅m/s submitprevious answers correct part b if it takes the ball 20 s to stop once it is in contact with the catcher's glove, what average force did the ball exert on the catcher? express your answer in newtons.

To solve this problem we need the concepts related to Energy in terms of momentum and the average force of a body given by Newton's second law.

Energy in terms of momentum is given by the equation

Where,

m=mass

v=velocity

Part A) For the first part we understand that the impulse would be,

Part B) For part B the average force is given by,

Where,

m = mass

a = acceleration, which is also given by
