Question

A body does $50J$ of work in $5seconds$. What is its power?

Answer 1

Step 1: Given data:

1. Work done$=$$50J$
2. Time taken$=5s$

Step 2: Calculating power by applying formula:

$Power\left(P\right)=\frac{Workdone\left(W\right)}{Timetaken\left(t\right)}$

$P=\frac{50J}{5s}=10W$

Hence, the power of a body is $10W$.
