A car was movig at a rate of `18 kmh^(-1)` . When the brakes were applied, it comes to rest in a distance of 100 m. Calculate the retardation produced by the brakes.

A car was moving at a rate of 18 km/h. When thebrakes were applied, it comes to rest in a distance of 100 m. Calculate the reterdation produced by the brakes.

Brakes are applied to a car traveling at 30" ms"^(-1) . Its velocity is reduced to 20" ms"^(-1) in 5 seconds. Calculate the retardation produced by the brakes. Also calculate the distance covered in those 5 seconds.
