Question

Question based on graph
31. In the following graph variation with time (t), in velocity (v) of a particle moving rectilinearly is
shown. What is average velocity in m/s of the particle in time interval from 0 s to 4 s?


​

Answer 1

Answer:

3m/s

Explanation: avg. velocity = net displacement/time

here calculate the area of the both rectangles which gives us the displacement . the net displacement is 12 meter

then time is 4sec after calculation the average velocity is 12/4=3m/s.
