A solid horizontal surface is covered with a thin layer of oil. A rectangular block of mass$m=0.4kg$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$v\left(t\right)=v_0{e}^{-\frac{t}{\tau }}$, where$v_0$is a constant and$\tau =4$. The displacement of the block, in meter, at$t=\tau$is __________. Take$e^{-1}=0.37$
