**Physics of Inclined Plane: Practical Example**

A 320-kg piano slides 3.9 meters down a 25-degree incline. The piano is prevented from accelerating by a man exerting a force parallel to the incline.

**Diagram Explanation:**

The image illustrates a scenario involving a large grand piano sliding down an inclined plane. The incline is set at a 25-degree angle relative to the horizontal surface. A man is depicted pushing against the piano to prevent it from accelerating further down the slope. His force is applied parallel to the inclined plane, indicating the importance of understanding vectors and forces in action on inclined surfaces.

This example is useful for studying concepts like gravitational force components, normal force, friction, and net force acting on objects on an inclined plane.

**Part D**

Determine the net work done on the piano. Ignore friction.

**Express your answer using two significant figures.**

Below the prompt is a text box labeled "W =" followed by a space to input the answer. There are options for formatting, including a square root and power symbol, and a variable symbol. Additionally, there are undo, redo, and reset buttons, as well as a keyboard input option. The unit "J" for Joules is indicated next to the input box.
