What is the work done to move a body of
mass 60 kg to a distance of 5 meters, if the co-
efficient if friction between body and the plane is
0.2?
A: 12 kg
B: 60 kg
C 12 m-kg
D 60 m-kg​

Answer 1

Answer:

Work is the force exerted on an object times the distance over which the force is exerted: W = Fx, where W is the work in Nm = Joule. Work done to lift an object of mass m a height h: W = Fgh = mgh. Work done against friction: W = Ff x.

Step-by-step explanation:

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.
