Two billiard balls \(A\) and \(B,\) each of mass \(50~\text g\) and moving in opposite directions with a speed of \(5~\text{m/s}\) each, collide and rebound at the same speed. If the collision lasts for \(10^{-3}~\text s, \) then;
| (a) | the impulse imparted to each ball is \(0.25~\text{kg-ms}^{-1}\) and the force on each ball is \(250~\text N\) |
| (b) | the impulse imparted to each ball is \(0.25~\text{kg-ms}^{-1}\) and the force exerted on each ball is \(25\times 10^{-5}~\text N\) |
| (c) | the impulse imparted to each ball is \(0.5~\text{N-s}\) |
| (d) | the impulse and the force on each ball are equal in magnitude and opposite in direction. |
Which of the following statement(s) is/are true?
| 1. | (a) and (c) only |
| 2. | (a) and (b) only |
| 3. | (c) and (d) only |
