Three particles with equal mass move with equal speed `v` along the medians of an equilateral triangle as shown. They all collide at the centroid simultaneously. After the collision. `A` comes to rest, `B` retraces it's path with same speed. What is speed of `C` after the collision?

A

`v`

B

`v//2`

C

`2v`

D

Text Solution

Verified by Experts

The correct Answer is:
A
`P_(i)=0`
`P_(i)=0`, So speed of C id equla to that of B and moving in opposite direction.
So Ans. Is v.

Two bodies A and B of masses m and 2 m respectively are placed on a smooth floor. They are connected by a spring. A third body C of mass m moves with velocity v_0 along the line joining A and B and collides elastically with A as shown in Fig. At a certain instant of time t_0 after collision, it is found that the instantaneous velocities of A and B are the same. Further at this instant the compression of the spring is found to be x_0 . Determine (i) the common velocity of A and B at time t_0 , and (ii) the spring constant.
