A particle of mass ``m`` moving with velocity v strikes a particle of mass ``2m`` at rest and sticks to it. The speed of the combined mass is

A

`v/2`

B

2v

C

`v/3`

D

`v/4`

Text Solution

Verified by Experts

The correct Answer is:
C
According to conservation of linear momentum
`mv=(m+2m)v^(1)`
`v_(1)(mv)/(3m)=v/3`

A ball of mass m moving with a velocity v along X-axis, strikes another ball of mass 2m kept at rest. The first ball comes to rest after collision and the other breaks into two equal pieces. One of the pieces starts moving along Y-axis with a speed v_1 . what will be the velocity of the other piece?

    A block of mass m and a pan of equal mass are connected by a string going over a smooth light pulley as shown in figure. Initially the system is at rest when a particle of mass m falls on the pan and sticks to it. If the particle strikes the pan with a speed v find the speed with which the system moves just after the collision.
