A particle starts from rest. Its acceleration at time t=0 is `5 m//s^(2)` which varies with time as shown in the figure. The maximum speed of the particle will be

A

`16/7 m//s`

B

`24/7 m//s`

C

`20/7 m//s`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
B
Average speed
`=("Distance")/("time")=(20+40+60+80+40)/70=24/7 m//s`
