An Object with a Mass of 10 Kg Is Initially

question 112

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
