a) how much work is done in raising a 50.0 kg crate a distance
of 1.5 m above a storeroom floor?
b) what is the change of potential energy as a result of this
move?
c) how much kinetic energy will the crate have as it falls and hits
the floor?
please show work
a) how much work is done in raising a 50.0 kg crate a distance of 1.5 m above a storeroom floor?
Work = Fd = mg h = 50.0 x 9.81x 1.5= 736 j (or 740 J using 2 S.F.)
b) what is the change of potential energy as a result of this
move?
ΔPe = mg Δh= 50.0 x 9.81x 1.5= 740 J
c) how much kinetic energy will the crate have as it falls and hits
the floor?
Kinetic energy at the very bottom is equal to potential energy at the very top
Pemax= Kemax = 740 J
please let me know if you have any questions.

Please show work for each part. A factory worker pushes a 26.5-kg crate a distance of 4.3 m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and the floor is 0.27 Suppose the worker pushes downward at and angle of 340 below horizontal. (a) What magnitude of force must the worker apply? (b) How much work is done on the crate by this force? (c) How much work...
