Explain the forces acting on an object sliding down a snowy mountain inclined at an angle θ. Include the roles of gravitational force, normal force, and friction.
A box weighing 50 kg is sliding down a snowy incline at a constant speed. If the incline makes an angle of 30 degrees with the horizontal, calculate the force of friction acting on the box.

Quick comprehension check
“A sled weighing 80 kg is sliding down a snowy incline that makes an angle of 25 degrees with the horizontal. Calculate the force of friction acting on the sled if it is moving at a constant speed. Show all work. A snowboarder with a mass of 65 kg is descending a snowy slope inclined at an angle of 30 degrees. Determine the force of friction acting on the snowboarder if they maintain a constant velocity. Show all work.”
