Question
**Physics Problem: Inclined Plane** A 360 kg piano slides 2.6 meters down a 24° incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. Ignore friction. ### Diagram Description The diagram (Figure 1) shows a man pushing against a grand piano to prevent it from sliding down an inclined plane. The incline is at a 24° angle to the horizontal. The man's force counteracts the piano's tendency to slide down the slope. ### Parts of the Problem **Part A** - Determine the force exerted by the man. - Given Answer: \( F_p = 1400 \, \text{N} \) **Part B** - Calculate the work done by the man. - Given Answer: \( W_p = 3.7 \, \text{J} \) **Part C** - Determine the work done against gravity. (Note: Details for Part C are not included in the image. Further information would be required for calculations.) ### Explanation This exercise involves physics concepts such as forces on an incline, work, and energy. The figure helps illustrate how force is applied to counteract gravitational pull along the plane.
