A man moves on a straight horizontal road with a block of...

A man moves on a straight horizontal road with a block of mass $2 \mathrm{~kg}$ in his hand. If he covers a distance of $40 \mathrm{~m}$ with an acceleration of $0.5 \mathrm{~m} / \mathrm{s}^{2}$, find the work done by the man on the block during the motion.

Key Concepts

Work-Energy Theorem

The work-energy theorem connects work and kinetic energy by stating that the net work done on an object is equal to the change in its kinetic energy. This theorem is pivotal in understanding how forces affect the energy state of a moving object.

Work

Work is the transfer of energy by means of a force causing a displacement. It is calculated as the product of the force component in the direction of the displacement and the displacement itself.

Newton's Second Law

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = m × a). This principle is fundamental in determining the force required to accelerate an object over a distance.
