Physics

a box of mass m = 66.0 kg (initially at rest) is pushed adistance d = 54.0 m across a rough warehouse floor by an appliedforce of FA = 218 N directed at an angle of 30.0° below thehorizontal. The coefficient of kinetic friction between the floorand the box is 0.100. Determine the following. (For parts (a)through (d), give your answer to the nearest multiple of 10.) * Ialready solved parts b and c so I didn't include them.

a)work done by the applied force WA =

d)work done by the force of friction Wf =

e) Calculate the net work on the box by finding the sum of allthe works done by each individual force. WNet = J

f)Now find the net work by first finding the net force on thebox, then finding the work done by this net force. WNet = J
