Question

For the displacement - time graph shown in figure, the ratio of the magnitudes of the speeds during the
first two second and the next four second is

Answer 1

Answer:

Slope of displacement-time curve gives the speed.

For first 2 seconds, speed v= 40/2 =20 m/s

For the last 4 seconds, speed v= 40/4 =10 m/s

Hence, ratio =20/10=2:1
