A car moving with a velocity of 10m/s can be stopped by the application of a constant force F In a distance of 20m. If the velocity of the car is 30m/s. It can be stopped by this force in

`(20)/(3)m`

20 m

60 m

180 m

Text Solution

Verified by Experts

The correct Answer is:

`S prop u^(2)`. If u becomes 3 time, then S will become 9 times i.e., `9xx20=180 m`
