Candice goes skiing on her March Break. She notices that the skiers are approaching the lift at too great a speed. She designs a ramp, 14 m long, inclined at 20 degree celsius to the horizon, to slow the skiers down from an average speed of 12 m/s to a speed of 2 m/s. She needs to find a surface material with the right coefficient of friction.
a) Draw a free body diagram of a skier on the ramp.
b) What coefficient of friction does she need?

Renee is on Spring Break and pulling her 21-kg suitcase through the airport at a constant speed of 0.47 m/s. She pulls on the strap with 120 N of force at an angle of 38° above the horizontal. Assume the ground to be flat, Draw a FBD showing the forces on the suitcase. Find the acceleration of the suitcase. Determine the normal force experienced by the suitcase. Determine the total resistive force (friction) experienced by the suitcase. Find the coefficient...
