You are lowering two boxes, one on top of the other, down the ramp shown in the figure by pulling on a rope parallel to the surface of the ramp. Both boxes move together at a constant speed of 15.0 cm/s. The coefficient of kinetic friction between the ramp and the lower box is 0.486, and the coefficient of static friction between the two boxes is 0.823. ▶ ▶ Part A You may want to review (Page) For help with math skills, you may want to review: Resolving Vector Components Calculating Trigonometric Function Values For general problem-solving tips and strategies for this topic, you may want to view a Video Tutor Solution of Toboggan ride with friction II.

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
