Figure shows the position-time (x-t) graph of one dimensional motion of a mass 500g. What is the time interval between two consecutive impulses received by the body?

Options

A. 2s
B. 4s
C. 6s
D. 8s

Answer

A

Explanation

Figure shows that slope of `x-t` graph change from positive to negative at `t=2s` , and it changes from negative to positive at `t=4s` and so on. Thus direction of velocity is reversed after every two seconds. Hence, the body must be receiving conseccutive impulses after every two second.
