Question

A (physically, but not biologically, accurate) cartoon superhero stops a speeding bullet (mass 43.5 g and initial velocity 515 m/s) by catching it with his hand.

Assume the bullet does not penetrate or break his hand in any way.

Part A: During the catch, the hand moves backward a distance of 10.0cm while bringing the bullet to a stop. What is the average force the hand exerts on the bullet? Answer is in N

Part B: How much time elapses from the start of the catch until bullet stops moving? Give your answer in milliseconds. Note: you could solve this using conservation of momentum or using kinematics (if you assume a constant acceleration during the catch). It's a good idea to try both. Answer is in ms

Answer 1

Hello student

In this given problem we assume constant acceleration durind catch and we solve this problem using kinematics. If we try to solve using conservation of linear momentum then problem get more complicated.

If you satisfy with my answer then give a thumbs up.

Thank you!
