A boy pulls a toy cart across a flat room with a force of $5$ N, moving it over a distance of $4$ m. How much work is done by the boy on the cart?
  1. $1$ J
  2. $9$ J
  3. $20$ J
  4. $0.8$ J

Solution

Work done is calculated as $\text{Force} \times \text{Distance}$. Here, $5\text{ N} \times 4\text{ m} = 20\text{ J}$.
