Figure shows the position-time graph of a body of mass 0.04 kg. Suggest a suitable physical context for this motion. What is the time between two consecutive impulses received by the body ? What is the magnitude of each impulse ?

Text Solution

Verified by Experts

A body with a constant speed of `1 cm s^(-1)` receives impulse of magnitude `0.04 kg xx 0.02 m s^(-1) = 8 xx 10^(-4) kg m s^(-1)` after every 2 s from the walls at x = 0 and x = 2 cm.
