Momentum and CollisionMedium
Question
A particle of mass m moving with velocity v collides with a stationary particle of mass2m. Then the speed of the speed of the system after collision is:
Options
A.2v
B.
C.3v
D.
Solution
Applying conservation of momentum,
mv + 0 = (2mv + mv) v = 3mv
v′ =
mv + 0 = (2mv + mv) v = 3mv
v′ =
