A rope tow is used to move snow skiers along a 40 degree incline. The tow carries 50 skiers with an average mass of 80.0kg (the skiers hold onto the rop as it pulls them up the hill. The coefficient of kinetic friction between the skis and the snow is 0.12. a) What total force must the winch at the top of the hill exert to pull a full complement of skiers up the hill at constant speed? Draw the FBD. Show your work. (3 pts) b) If the hill is 800.0 m long and a skier starts from rest at the top, accelerates for the first 3 seconds and then continues at constant speed until they reach the bottom, how long will the descent take? Include FBD (4 pts)
