Question

The given figure shows the displacement – time graph of a body moving a in a straight line. The velocity of the body during the last 10 seconds is
A. 2 m/s
B. 0 m/s
C. 3 m/s
D. 2.5 m/s

Answer 1

Answer:

displacement (s) :70 - 40 = 30 m

time (t) : 45-35 = 10 s

velocity = s/t

            = 30/10

           = 3 m/s

therefore the answer is OPTION C : 3 m/s
