How much work did the movers do to push a 47.0 kg crate 10.2 m across a rough floor at a speed of 2.2 m/s with a horizontal pushing force of 58 N ?

Expert Solution

Work W = F.S , work done by all force = chang in its kinetic energy W = KE + (FS) W = 1/2 M V²+FS W = (1/2).47.(2.2)²+ 58.(10.2) = 705.34 J

Work on a sliding crate. A worker pushes a 47.0 Kg crate across a level horizontal floor by applying a constant force of exactly 150.0 N at an angle of 23.0 degrees below the horizontal. The crate begins at rest and ends 15.0m from where it started traveling at 2.6m/s A. What is the work done by the applied force as the crate moves across the floor? B What is the work done by the friction force as the crate...

Movers push an 80 kg trunk at 1.0 m/s when they encounter a 2.5 m long stretch of floor where the coefficient of kinetic friction is 0.30. During this stretch of floor, the movers push the trunk with 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 the trunk at the end of the 2.5...
