The area of F-t curve is A, where 'F' is the force on one mass due to the other. If one of the colliding bodies of mass M is at rest initially, its speed just after the collision is :

A

A/M

B

M/A

C

AM

D

`sqrt((2A)/(M))`

Text Solution

Verified by Experts

The correct Answer is:
A

Area of F-t curve=A=Impulse
Impulse=dP=A=Mv-0
`therefore v=A/M`
