For these questions use g = 9.80 m/s. You, with m = 75 kg, have just come down a ski slope and are traveling at 18.0 m/s. You continue to slide on the flat terrain at the bottom of the hill, being slowed by frictional forces. It takes 7.30 s for you to come to a stop. Question 14 == Homework Unanswered Calculate the coefficient of kinetic friction between your skis and the snow. A young parent is dragging a 640 N sled (this includes the weight of two kids) across some snow on flat ground, by means of a rope attached to the sled. The rope is at an angle of 30 degrees with respect to the horizontal and the tension in the rope is 160 N. The sled is moving at a constant velocity of 1.5 m/s. Question 15 == Homework Unanswered Determine the normal force applied by the ground on the sled. N Question 16 == Homework Unanswered Calculate the coefficient of kinetic friction between the sled and the snow. == Question 8 Homework Answered Taking down the ramp to be the positive direction, what is the expression for the crate's acceleration as it is coming down the ramp?
