An inelastic collision takes place between ball of known masses, just before the collision one of the ball is moving with a known velocity while the other is stationary. Which of the following physical quantities can be determined from the information given?
- speed of each of the ball after collision
- kinetic energy of each ball after collision
- total momentum of the ball after collision
-
total momentum of the two ball after collision
- mutual forces excerted by the balls
The correct answer is: D
Explanation
The total momentum of the two balls after collision:
Can be determined. The total momentum before the collision can be calculated using the mass and velocity of the moving ball, and since momentum is conserved, the total momentum after the collision will be equal to the total momentum before the collision
