Answer:1834.56 joules
Explanation:
Distance=36m
Coefficient of friction=0.2
Mass=26kg
Acceleration due to gravity=9.8m/s^2
Reaction=mass x acceleration due to gravity
Reaction=26 x 9.8
Reaction=254.8N
Coefficient of friction=frictional force ➗ reaction
0.2=frictional force ➗ 254.8
Frictional force=0.2 x 254.8
Frictional force=50.96N
work=friction force x distance
Work=50.96 x 36
Work=1834.56
Work=1834.56 joules
