7 questions

1

Define the relationship between the force of kinetic friction, the coefficient of kinetic friction, and the normal force.

2

A box with a weight of 50 N is resting on an inclined plane angled at 30° to the horizontal. What is the normal force acting on the box?

Quick comprehension check

A 5 kg block is resting on an inclined plane angled at 25° to the horizontal. The coefficient of static friction between the block and the plane is 0.4. Calculate the force of friction acting on the block. Show all work. A box with a mass of 8 kg is on an inclined plane that makes an angle of 30° with the horizontal. If the coefficient of kinetic friction between the box and the plane is 0.3, what is the force of friction acting on the box as it slides down the plane? Show all work.
