JEE · NEET Previous Year Question
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
Topic: JEE PYQ
Answer: A. Full step-by-step solution below.
- A
- B
- Cv
- D
Correct answer: A
Solution
(a)The law of conservation of momentum is given as
u + u' =( + )v'
The given data is
u = v
u' =
=m
= 2m
Using the conservation of momentum equation,
mv + 2m (0) = (m + 2m) v'
