Question

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 N ,s is applied to the block at time t=0 so that it starts moving along the x-axis with a velocity v(t)=v_0e^ -t/ , where v_0 is a constant and =4 s. The displacement of the block, in *metres*, at t= is _____. Take e^ -1 =0.37.
