Humans can produce an output power as great as $20 \mathrm{W} / \mathrm{kg}$ during extreme exercise. Sloths are not so energetic. At its maximum speed, a 4.0 kg sloth can climb a height of $6.0 \mathrm{m}$ in 2.0 min. What's the specific power for this climb?

Key Concepts

Mechanical Work

Mechanical work in this context is the energy required to move an object against gravitational force, calculated as the product of mass, gravitational acceleration, and height. This concept forms the basis for determining the energy needed to elevate an object to a higher altitude.

Power

Power is defined as the rate at which work is performed or energy is transferred over time. It is calculated by dividing the total work done by the time taken to do that work, providing a measure of how quickly energy conversion occurs.

Specific Power

Specific power refers to the power output per unit mass. It is a useful measure in comparing the energy efficiency or performance of systems, such as muscles in biological organisms, by normalizing power relative to its mass.

Gravitational Potential Energy

Gravitational potential energy is the energy that an object possesses due to its position in a gravitational field. It is directly proportional to the object's mass and the height to which it is raised, making it a key factor in analyzing work done during elevation changes.
