A 50 kg mass is travelling at a speed of 2 m/s. Another 60 kg
mass travelling at a speed of 12 m/s in the same direction,
strikes the first mass. After the collision the 50 kg mass is
travelling with a speed of 4 m/s. The coefficient of restitution
of the collision is
a) 19/30
b)30/19
c)20/11
d)11/20

Answer:
Coefficient of restitution for the collision is 19/30
Explanation:
As we know that there is no external force on the system of two mass
So here we can use momentum conservation for the collision
So we will have
now we have
now by formula of coefficient of restituition we will have
here we will have
