A sphere of mass m moving with a constant velocity hits another stationary sphere of the same mass. If e is the coefficient of restitution, then ratio of speed of the first sphere to the speed of the second sphere after head on collision will be :
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
mu = mv 1 + mv 2 .......(i)
u = v 1 + v 2 .......(ii)
= e ......(iii)
on solving we have
=
