Starting from rest, a 6.79 kg block slides 2.82 m down a rough 20.7 ◦ incline. the coefficient of kinetic friction between the block and the incline is 0.425. the acceleration of gravity is 9.8 m/s 2 . find the work done by the force of gravity. answer in units of j.

23.52092 J

Explanation:

m = Mass of block = 6.79 kg

s = Sliding distance = 2.82 m

= Angle of slide = 20.7°

= Coefficient of kinetic friction = 0.425

g = Acceleration due to gravity = 9.8 m/s²

Work done by the force of gravity is given by

The work done by the force of gravity is 23.52092 J
