The velocity- time graph of car moving on a straight track is given below. The car weight 1000kg.
The braking force rewquired to boring the car to a stop with in one second from the maximum speed is:

A

`(10000)/3N`

B

`5000N`

C

`10000N`

D

`(5000)/3N`

Text Solution

Verified by Experts

The correct Answer is:
C
Retardation `=(10ms^(-1))/5 =10ms^(-2)`
:. Braking force =ma `=1000xx10=10000` N
Hence(C)
