Question

A ball of mass $600$ grams strikes a wall with a velocity of $5m/s$ at an angle $30$ degree with the wall and rebounds with the same speed at the same angle with the wall. the change in momentum of the ball is

• A. $3kgm{s}^{-}1$
• B. $1kgm{s}^{-}1$
• C. $0.25kgm{s}^{-}1$
• D. zero

Answer 1

The correct option is A $3kgm{s}^{-}1$

Mass$=0.6kg$

velocity$=5m/s$

change of momentum $=3kgm/s$

Hence,

option $\left(A\right)$ is correct answer.
