A riding ball of mass m strikes a rigid ...

A riding ball of mass `m` strikes a rigid wall at `60^(@)` and gets reflected without loss of speed as shown in the figure below. The value of impulse imparted by the wall on the ball will be.

A

`(mV)/(2)`

B

`(mV)/(3)`

C

`(mV`

D

`3 mV`

Text Solution

Verified by Experts

Impulse `=|bar(Delta P)| = |bar (m Delta V)| = m (2 V cos 60^(@)) = mV`
