Question 388033: A box whose weight is 182kg is drawn with constant speed 21m along a horizontal concrete floor. the kinetic friction between the box and the floor is 0.58.
Calculate the work done when the box is drawn with horizontal force.
( g = 9.81 m/s^2 )

W=Fd
Calculate the friction force,
F%5Bf%5D=mu%2AN=mu%2Amg
F%5Bf%5D=0.58%2A%28182%29%289.8%29
F%5Bf%5D=1034.5Newtons
Then
W=F%5Bf%5D%2Ad
W=1034.5%2A21
W=21724 Joules
