Velocity-time graph for a moving object ...

Velocity-time graph for a moving object is shown in the figure. Total displacement of the object during the time interval when there is non-zero acceleration and retardation is.

A

60m

B

50m

C

30m

D

40m

Text Solution

Verified by Experts

The correct Answer is:
B
Distance travelled = Area under v −t graph in time interval 20 to 40 sec
` = 1/2 xx 20 xx 3 + 20 xx1 = 50m`
