STANDARD Physics Graphs of Motion MCQ Question
Type: MCQ-conceptual-Medium
Figure shows the position-time (x-t) graph of one dimensional motion of a body of mass 500 g. What is the time interval between two consecutive impulses received by the body?
A
2 s
B
4 s
C
6 s
D
8 s
Correct Answer
Option A
Detailed Explanation
Figure shows that slope of x-t graph changes from positive to negative at t = 2 s, and it changes from negative to positive at t = 4 s and so on. Thus direction of velocity is reversed after every two seconds. Hence, the body must be receiving consecutive impulses after every two seconds.
