Question

A and B are two bodies having same mass. B
is kept at rest and A is made to strike B with
some velocity. If the collision is elastic then
A A and B both come to rest
A moves with a greater velocity than
B
B
с
A and B both move with same
velocity
D
A comes to rest while B moves with
the velocity equal to the initial
velocity of A​

Answer 1

Answer:

D.

Explanation:

in elastic collision

• momentum is conserved

•no loss in kinetic energy..that also means Ki=Kf

•e=1,means velocity of separation= velocity of approach

P conservation

mv + m(0)=mVa + mVb

v=Va+ Vb

e equation

v =vb-va

from abone eq. you will get that

velocit of b will be equal to initial velocity of A
