Acceleration time graph of a particle mo...

Acceleration time graph of a particle moving along a straight line is given. Then average acceleration between `t=0` & `t=4` is `:-`

A

`0m//s^(2)`

B

`5m//s^(2)`

C

`10m//s^(2)`

D

`7.5m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Average acceleration `=(Deltav)/(Deltat)`
`Deltav=`area`=(1)/(2)xx4xx10=20`
Average acceleration`=(20)/(4)=5m//s^(2)`
