A particle of mass m 1 moves with speed u 1 and collides head on with a stationary particle of mass m 2 . After the collision, the velocities of the particles are v 1 and v 2 and e is coefficient of restitution for the collision. If v 1 is to be positive, i.e., for the first particle to continue moving in the same direction then:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
v 1 > 0
⇒ ⇒ 
⇒ ⇒ m 1 – m 2 e > 0
⇒ ⇒
