Abody of mass 400 kg is suspended at a lower end of a light vertical chain and is being pulled up vertically. initially the body is at rest and the pull on the chain is 6000 g (g is 9.8 m/s^2) the pull gets smaller uniformly at the rate of 360g n per each meter through which the body is raised. what is the velocity of the body when it has been raised 10m?
