Options:

Momentum of table-tennis ball is higher than cricket ball

Momentum of cricket ball is higher than table-tennis ball

Both Table-Tennis and cricket ball possess same momentum

Momentum of Table-tennis ball is zero and that of cricket ball is negative

Correct Answer:

Momentum of cricket ball is higher than table-tennis ball

Explanation:

During the game of table tennis if the ball hits a player, it does not hurt him. On the other hand, when a fast-moving cricket ball hits a spectator, it may hurt him.

Cricket ball possess higher momentum than Table-tennis ball.

These observations suggest that the impact produced by the objects depends on their mass and velocity. 

The momentum, p of an object is defined as the product of its mass, m and velocity, v. That is, p = mv
