The velocity of a bullet is reduce from `200 m//s` to `100m//s` while travelling through a wodden block of thickness `10 cm` Assuming it to be uniform, the retardation will be

The velocity of a bullet is reduced from 200 m//s to 100 m//s while travelling through a wooden block of thickness 10 cm . The retardation, assuming it to be uniform, will be.

(a) If a train traveling at 72 km//h is to be brought to rest in a distance of 200 m , find the deceleration. (b) The velocity of a bullet is reduced from 200 m//s to 100 m//s while traveling through a wooden block of thickness 10 cm . Find the retardation (assuming it ti be uniform).

The velocity of a bullet is reduced from 400 ms^(-1) to 100 ms^(-1) while travelling thought material of thickness of 1 m. The retardation will be

The velocity of a bullet is reduced from 400 ms^(-1) to 100 ms^(-1) while travelling thought material of thickness of 1 m. The retardation will be

When a car driver travelling at a speed of 10 m/s applies brakes and brings the car to rest in 20 s, then retardation will be :

The speed of a train is reduced from 60 km/h, to 15 km/h,while it travels a distance of 450m.If the retardation in uniform,find how much further it will travel before coming to rest?

On observing a sign board about speed limit,a driver applies brakes and reduces his speed from 100m/s to 50m/s though a distance of 50m .The uniform retardation provided by the brakes (in m/ s^(2) ) will be ?
