Problem 4: Suppose the ski patrol lowers a rescue sled carrying an injured skiier, with a combined mass of 87.5 kg, down a 60.0° slope at constant speed, as shown in the Figure. The coefficient of kinetic friction between the sled and the snow is 0.100.

Part (a) How much work, in joules, is done by friction as the sled moves 28.5 m along the hill?

Part (b) How much work, in joules, is done by the rope on the sled over this distance?

Part (c) What is the work, in joules, done by the gravitational force on the sled?

Part (d) What is the net work done on the sled, in joules?

Problem 4. Suppose the weights of seventh-graders at a certain school vary according to a Normal distribution, with a mean of 100 pounds and a standard deviation of 7.5 pounds. A researcher believes the average weight has decreased since the implementation of a new breakfast and lunch program at the school. She ﬁnds, in a random sample of 35 students, an average weight of 98 pounds. What is the P-value for an appropriate hypothesis test of the researcher’s claim?
