A particle of mass m moving with velocity v collides with a stationary particle of mass 2m. After collision, they stick together and continue to move together with velocity
A
B
C
v
D
Text Solution
Verified by ExpertsThe correct answer is:
A
The law of conservation of momentum is given as
m 1 u + m 2 u' =(m 1 + m 2 )v'
The given data is
u = v
u' = 0ms -1
m 1 =m
m 2 = 2m
Using the conservation of momentum equation,
mv + 2m (0) = (m + 2m) v'
