a train starting from rest, is accelerated at the rate of 81km/hr^2 along straight rails. At the instant when it covers a distance of 50km,a ball is thrown horizontally from the top of the train with velocity of 10m/sec along the direction at right angles to the train`s motion. if the ball is projected at the height of 4m from the ground, the shortest distance it covers just before hitting the ground.
