A car of mass 1250 kg is moving at `30(m)//(s)`. Its engine delivers 30 kW while resistive force due to surface is 750 N. What maximum accelration can be given to the car

A

`(1)/(3)(m)//(s^2)`

B

`(1)/(4)(m)//(s^2)`

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
C

`Fv=P`
`Fxx30=30000`
`F=1000N`
`F-750=ma`
`1000-750=1250a`
`a=(1)/(5)(m)//(s^2)`
