Question
**Question 3:** Does the energy of the crate increase, decrease, or stay the same while the person is pushing on the crate? Explain. **Explanation:** When a person applies a force to push the crate, they are doing work on it by transferring energy from themselves to the crate. This results in an increase in the kinetic energy of the crate if it starts moving. The energy of the crate increases because the work done on it is converted into the kinetic energy, causing it to speed up and/or move from its initial position.

A person is pushing a wooden crate of mass \( m_0 = 20 \, \text{kg} \) at a constant speed \( v_0 = 1.2 \, \text{m/s} \) for \( \Delta x = 3 \, \text{m} \) along a rough horizontal floor that has a coefficient of friction \( \mu_k = 0.4 \).
