Answer:

a) Work = 200 Joules

b) The motor moved a distance of 3.08 meters

Step-by-step explanation:

Force, F = 65 N

Power, P = 20 W

Time, t = 10 seconds

a) Calculate the work done

Power = Work / Time

20 = Work / 10

Work = 20 x 10

Work = 200 Joules

b) How far did it move?

Work = Force x Distance

200 = 65 x Distance

Distance = 200/65

Distance = 3.08 m
