AP EAMCET · PHYSICS · Center of Mass Momentum and Collision
A ball moving with velocity \(2 \mathrm{~m} / \mathrm{s}\) collides head on with another stationary ball of double the mass. If coefficient of restitution is 0.5 , then their velocities (in \(\mathrm{m} / \mathrm{s}\) ) after collision will be :
- A \(0, 1\)
- B \(1, 1\)
- C \(1, 0.5\)
- D \(0, 2\)
Answer & Solution
Correct Answer
(A) \(0, 1\)
Step-by-step Solution
Detailed explanation
Let mass of first ball be \(m\) i.e. \(m_1=m\) Mass of second ball \(\mathrm{m}_2=2 \mathrm{~m}\) Velocity of first ball before collision \(\mathrm{u}_1=2 \mathrm{~m} / \mathrm{s}\) Velocity of second ball before collision \(\mathrm{u}_2=\mathrm{om} / \mathrm{s}\) Given :…
