A horizontal force of 142 N is used to push a

47.0 kg packing crate a distance of 6.00 m on

a rough horizontal surface.

The acceleration of gravity is 9.81 m/s2 .

If the crate moves with constant velocity,

calculate

a) the work done by the force.

Answer in units of J

b) the coefficient of kinetic friction.
