The figure given below shows position-time graph of a particle of mass 0.04 kg. Suggest a suitable physical context for the motion. What is the time between two consecutive impulses received by the particle ? What is the magnitude of each impulse ?
Physical context: Given graph can be a graph of a ball rebounding between two walls situated at position 0 cm and 2 cm. The ball is rebounding from one wall to the another time and again every 2 s with uniform velocity.
Note : Negative sign indicates the universal direction of motion. We can visualize the balls getting rebounded repeatedly on striking against the wall. The linear momentum changes after every collision.
