Physics-Angular Momentum
NEET Physics Angular Momentum MCQ Question
Type: MCQ-numerical-Easy-Class 11
Two particles of masses m1 and m2 collide elastically. If the initial velocity of m1 is v1i and it comes to rest after the collision, what is the final velocity v2f of m2?
A
v2f = v1i * m1 / m2
B
v2f = (v1i * (m1 + m2)) / m1
C
v2f = v1i
D
v2f = 0
Correct Answer
Option A
Detailed Explanation
Using conservation of linear momentum and the fact that m1 comes to rest, m1 * v1i = m2 * v2f. Thus, v2f = v1i * m1 / m2.
