kita hitung dahulu gaya gesekan yang bekerja pada benda:
fs = μs.N
sedangkan: N + F sin θ = w → N = w - F sin θ
N = 200 - (100 . 0,5)
N = 150 N
fs = 0,4 . 150
fs = 60 N.
fk = μk.N
fk = 0,2 . 150
fk = 30 N
W = (F . cos 30 - fk). s
s = 1/2 . a . t²
s = 1/2 . (F . cos 30° / m) . 60²
s = 1/2 . (100 . 0,866 / 20) . 3600
s = 7794 m
W = (100 . 0,866 - 30). 7794
W = 441.140,4 J
