In a direct impact loss in kinetic energy is given by
`Delta K = (M_(1)M_(2))/(2(M_(1) + M_(2)))(V_(1) - V_(2))^(2) (1- k^(2))`
with usual notations (except k) The quantity k will have dimensional formula

A

`[M^(0)L^(2)T^(-2)]`

B

`[MLT^(-1)]`

C

`[M^(0)L^(0)T^(0)]`

D

`[M^(0)T^(-1)]`

Text Solution

Verified by Experts

The correct Answer is:
c
It is clear that
`[1 - k^(2)] = M^(0)L^(0)T^(0)`
Hence `[k] = M^(0)L^(0)T^(0)`
Actually k is the coefficient of restitution
