you push a block of 50kg with a force of 400 N over a distance of 8m. How much kinetic energy does the box gain?

Identify the arrows that show the correct direction of heat transfer. 66°f 112°f 98°f

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively
