Question

Figure given below shows the variation of velocity with
time for a particle moving along a straight line, the
average velocity, during the entire motion is
(a) 15 m/s
(b) 7.5 m/s
(c) 6.25 m/s
(d) 13.75 m/s

Answer 1

Answer:

average velocity= 0*10+1*20+2*20++3*10+4*10/1+2+3+4

average velocity=0+20+40+30+40/10

average velocity=130/10=13 meter per second
