A solid horizontal surface is covered with a thin layer of oil. A rectangular block of mass m = 0.4 kg is at rest on this surface. An impulse of 1.0 Ns is applied to the block at time t = 0 so that it starts moving along the x-axis with a velocity , where v 0 is a constant and t = 4 s. The displacement of the block, in meters, at t = is _________. Take e -1 = 0.37.
