It takes a student t = 8.8 s to push a block m = 11 kg at a constant velocity over a distance of d = 9.1 m. The coefficient of friction between the block and the ground is μ = 0.31.
give equation Fs in terms of t, m, d, and μ
a) F = friction
F = u*mg
F = 0.31*9.8*11 = 33.41 N
E = 33.41*9.1 = 304 J
c) power = E/t = 304/8.8 = 34.54 W
