A box slides across a frictionless floor with an initial speed v = 2.2 m/s. It encounters a rough region where the coefficient of friction is µk = 0.2.

a) What is the shortest length of rough floor which will stop the box?

b) If instead the strip is only .8643 m long, with what speed does the box leave the strip?
