Bricks are passed on by one labourer to another at a height 3m from the ground, by being thrown upwards from the ground level.Bricks reach the second labourer, at a speed of 3 m*s^(-1). If the bricks were thrown up in such a way that they would reach the second labourer, at zero speed, what fraction of the work done by the thrower would have been saved ?
