Solution

Step 1: Given data,

Mass of the body, m=20kg

Distance covered, D=8m

Force applied,F=20N

Time taken, t=10s

Step 2: Finding the work done and power consumed,

The formula for work done, W=F×D

Putting values of F and D, W=20×8=160J

The formula for power consumed, P=Wt=16010=16Js-1

Hence, the work done is 160J and the power developed is 16Js-1
