AP EAMCET · PHYSICS · Center of Mass Momentum and Collision
Two balls and , of masses and respectively collide each other. If the ball A moves with a speed of and collides with ball moving with speed in the opposite direction. After collision if ball A comes to rest and the coefficient of restitution is (one), then the speed of the ball before it collides with ball is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Applying conservation of linear momentum before and after collsion, M150+2Mv=M0+2Mv'⇒150+2v=2v' ⇒v'=75+v ....1 Now, coefficient of restitution is given by e=v'-0150-v=1…
