**Problem 3: Pig Pushes Crate**A scenario is depicted where a pig is pushing a 20 kg crate across a barn floor. Initially, the crate has a kinetic energy given by \( E_k = 30 \, \text{J} \). The pig applies a steady force of 7 N on the box, while the kinetic frictional force opposing the movement of the box is 5 N. The question posed is: Once the box has moved 3 meters to the right, what will be its new kinetic energy?**Illustration Description:**The image shows a pig pushing a box, represented by a square with crossed lines, towards the right. An arrow indicates the direction of the force applied by the pig. The initial and final positions of the box are marked, with a horizontal line to indicate the surface.

3. A helpful pig pushes a 20kg crate across the barn floor. Initially, the crate has a kinetic energy of E, = 30J. The pig applies a steady force of 7N on the box, and the kinetic frictional force of the floor on the box is 5N. Once the box has moved 3m to the right, what is the kinetic energy of the box?
