Question

A body of mass 20 kg is dragged through a distance of 8m in 10 s by a force of 20 N.Find the work done by the force and the power consumed

Answer 1

Answer:

160joule

Explanation:

• work done=force×displacement. 20N×8m=160J

Answer 2

Explanation:

A=

mass = m = 2 kg

distance = s = 8 m

time = t = 10 s

force = F = 20 N

work done = Force * displacement

= 20*8 = 160 Nm

power = work/time

= 160/10

= 16
