Solution

Step 1: Given data:
Power= $200 W$
Time= $4 s$
Force= $100 N$
Step 2: To find work,
Formula used: $w o r k d o n e = p o w e r \times t i m e$
W= $200 \times 4$
$= 800 J$
Thus, the work done in the given case is $800 J$ .
Step 3: To find displacement,
Formula used: $w o r k d o n e = f o r c e \times d i s p l a c e m e n t$
$d i s p l a c e m e n t = \frac{w o r k}{f o r c e}$
s= $\frac{800}{100} = 8 m$
Thus, the displacement in the given case is $8 m$ .
