A ball \(P\) of mass 0.5 kg moving with a velocity of \(10 \mathrm{~ms}^{-1}\) collides with another ball \(Q\) of mass 1 kg at rest. If the coefficient of restitution is 0.4 , the ratio of the velocities of the balls \(P\) and \(Q\) after the collision is
- A \(1: 7\)
- B \(2: 7\)
- C \(2: 5\)
- D \(5: 6\)
Answer & Solution
Correct Answer
(A) \(1: 7\)
Step-by-step Solution
Detailed explanation
\(\mathrm{m}_1=0.5 \mathrm{~kg}, \mathrm{u}_1=10 \mathrm{~ms}^{-1}, \mathrm{~m}_2=1 \mathrm{~kg}, \mathrm{u}_2=0, \mathrm{e}=0.4\) \(\therefore\) The velocity of balls after collision…
