A box slides across a frictionless floor with an initial speed v = 4.9 m/s. It encounters a rough region where the coefficient of friction is uk = 0.3.

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

x = m

b) If instead the strip is only 2.45 m long, with what speed does the box leave the strip?

Vf = ______m/s
