NEET 2018 Physics Collisions MCQ Question
A moving block having mass m₁ collides with another stationary block having mass 4m. The lighter block comes to rest after collision. When the initial velocity of the lighter block is v, then the value of coefficient of restitution (e) will be
0.5
0.25
0.8
0.4
Correct Answer
Detailed Explanation
The coefficient of restitution is calculated using the relative velocities of the blocks before and after the collision. Given that the lighter block comes to rest, the value of e can be determined.
