Two masses of 0.25 kg each moves towards...

Two masses of 0.25 kg each moves towards each other with speed 3 `ms^(-1)` and 1 `ms^(-1)` collide and stick together. The final velocity will be

A

`0.5ms^(-1)`

B

`2ms^(-1)`

C

`1ms^(-1)`

D

`0.25ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`m(v_1 -v_2 ) =(m+ m)v`
`implies v = (0.25 xx(3 -1))/(2xx0.5) = 1m//s`
