Question

Two people wish to push a big beer freezer weighing 2000 N up aramp inclined at an angle of 37.0o with the horizontal.The coefficient of kinetic friction between the freezer and theramp is 0.500. (a) What minimum force must the people exert toslide the freezer up the ramp? (b) What acceleration will thefreezer have if it is released and slides down the ramp? (c) If itslides 4.00 m down the ramp and strikes a heavy object, coming torest in 0.500 m, what average force does it exert on the heavyobject?

Explanation / Answer

Weight W = 2000 N

Angle = 37 degrees

Coeffcien tof kinetic friction = 0.5

(a). The minimum force must the people exert to slide thefreezer up the ramp
