Question

Problem 3:
 A 5-kg box slides down a ramp. The ramp is 1 m in length and inclined at an angle of 30° as
shown. The box starts from rest at the top. The surface friction coefficient is 0.28.
 1. Use energy methods to determine the speed of the box at the bottom of the ramp.
 2. How far does the box slide before stopping on the horizontal floor if it continues to experience
the same friction coefficient (µ = 0.28).

Answer 1

Answer:

When a body is in motion, it has resistance because the body interacts with its surroundings. This resistance is a force of friction. Friction opposes relative motion between systems in contact but also allows us to move, a concept that becomes obvious if you try to walk on ice. Friction is a common yet complex force, and its behavior still not completely understood. Still, it is possible to understand the circumstances in which it behaves
