Question

a plastic ball and a clay ball of equal masses, travelling in the same direction with equal speeds, strike against a vertical wall. From which ball does the wall receive a greater amount of momentum?

Answer 1

Momentum is the product of velocity and mass of an object.

P = m * v

The clay and plastic balls have the same velocity and mass moving in the same direction.

Hence, the momentum of each of the ball will be equivalent.

The product of both the balls will come same and hence the result will be same.

Answer 2

since the clay and the plastic ball have same mass,velocity and they are also moving in the same direction the result will be same.the wall will exert equal amount of momentum from both the balls
