An 18.5 kg box initially at rest is pushed 2.63 m along a rough, horizontal floor with a constant applied horizontal force of87.3509 N. If the coefficient of friction between box and floor is 0.393, findthe work done by the friction. The acceleration of gravity is 9.8m/s2 . Answer in units of J.
(part 2) Find the the final speed of the box.
Answer in units of m/s.
