Solution

Step 1: Given data,
Mass of the body, $m = 20 k g$
Distance covered, $D = 8 m$
Force applied, $F = 20 N$
Time taken, $t = 10 s$
Step 2: Finding the work done and power consumed,
The formula for work done, $W = F \times D$
Putting values of $F$ and $D$ , $W = 20 \times 8 = 160 J$
The formula for power consumed, $P = \frac{W}{t} = \frac{160}{10} = 16 J s^{- 1}$
Hence, the work done is $160 J$ and the power developed is $16 J s^{- 1}$
