An Object with a Mass of 10 Kg Is Initially

question 154

Multiple Choice

An object with a mass of 10 kg is initially at rest at the top of a frictionless inclined plane that rises at 30° above the horizontal. At the top, the object is initially 8.0 m from the bottom of the incline, as shown in the figure. When the object is released from this position, it eventually stops at a distance d from the bottom of the inclined plane along a horizontal surface, as shown. The coefficient of kinetic friction between the horizontal surface and the object is 0.20, and air resistance is negligible. Find the distance d.

• A) 5.0 m
• B) 10 m
• C) 15 m
• D) 20 m
• E) 25 m
