Physics

Movers push an 80 kg trunk at 1.0 m/s when they encounter a 2.5m long stretch of floor where the coefficient of kinetic frictionis 0.30. During this stretch of floor, the movers push the trunkwith a steady force of 220 N.

a. Determine the net force along the direction of motion

b. Determine the net work done on the trunk

c. Using the work-energy theorem, determine the speed of thetrunk at the end of the 2.5 m stretch.

Please show your work clearly and write step by step solutionincluding numeric substitutions and etc. To make it easier, pleasedo this in paper and include the pictures. thanks
