Two billiard balls of mass 0.05 kg each moving in opposite directions with 10 ms−1 collide and rebound with the same speed. If the time duration of contact is t = 0.005 s, then what is the force exerted on the ball due to each other?

Multiple Choice Options

  • A 100 N
  • B 200 N
  • C 300 N
  • D 400 N

Step-by-Step Verified Solution

Change in momentum of one ball
