The velocity-time plot is shown in figure. Find the average speed in time interval `t = 0` to `t = 40 s` during the period.

A

zero

B

`2.5 m//s`

C

`5 m//s`

D

none

Text Solution

Verified by Experts

The correct Answer is:

B

Distance covered `D = 2[(1)/(2) xx 20 xx 5] = 100 m`
Average speed `=(D)/(40) = (100)/(40) = 2.5 m//s`.
