If a train travelling at 72 km/h is to be brought to rest in a distance of 200m, then its retardation should be:-

If a train travelling at 72 mkh ^-1 is to be brouhgt to rest in a distance 200 m, then its retardation should 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).

A car moving along a straight highway with a speed of 126 km h^-1 is brought to a stop within a distance of 200 m. What is the retardation of the car (assumed uniform), and how long does it take for the car to stop?

A local train, travelling at 72 km/hr is brought to rest in 10 seconds by applying the brake. How much is the acceleration produced in this case? Also how much is distance (s) covered by the train before coming to rest?

A car moving along a straight highway with speed of 126 km h^(-1) is brought to a stop within a distance of 200 m. What is the retardation of the car (assumed uniform), and how long does it take for the car to stop ?
