A particle starts from rest at t=0 and moves in a straight line with an acceleration as shown below. The velocity of the particle at t=3 s is

A

`5"m/s"^(2)`

B

`6"m/s"^(2)`

C

`10"m/s"^(2)`

D

`15"m/s"^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Velocity= area under acceleration time graph
Velocity = `(5xx1)-(5xx1)+(5xx1)`
Velocity =`5-5+5=5"m/s"^(2)`
