A car is moving in a straight line with speed 18 km `h^(-1)` . It is stopped in 5 s by applying the brakes. Find the speed of car in `m s^(-1)` .

Text Solution

Verified by Experts

Initial speed = u= 18 km `h^(-1)`
Time = t=5 s
Final speed = 0
18 km `h^(-1) = ((18xx1000))/((1xx3600)) "m s"^(-1)`
= `5 m s^(-1)`
