AP EAMCET · PHYSICS · Center of Mass Momentum and Collision
A metal ball of mass moving with a velocity of has a head on collision with a stationary ball of mass . After the collision, if both balls move together, the loss in kinetic energy due to collision is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
The linear momentum remains conserved before and after the collision, therefore, ⇒2 kg×36×10003600 m s-1+3 kg×0=3 kg+2 kgvv=205=4 m s-1 The loss in kinetic energy is,…
