* Question Completion Status: QUESTION 5 4 points Save Answer A man pulls a 20-kg sled 60 meters along an angled hill with a force of 150 N, which elevates the man 29 meters above the bottom of the hill. The man then hops on his sled and slides from rest to the bottom of the hill back along his 60 meter path, during which a 239 N frictional force acts upon his sled. How much work in Joules does the man do on the sled in pulling the sled up the hill? QUESTION 6 4 points Save Answer A man pulls a 10-kg sled 59 meters along an angled hill with a force of 108 N, which elevates the man 30 meters above the bottom of the hill. The man then hops on his sled and slides from rest to the bottom of the hill back along his 59 meter path, during which a 148 N frictional force acts upon his sled. How much work in Joules does the man do against friction in pulling the sled up the hill? QUESTION 7 12 points Save Answer A 94-kg man pulls a 15-kg sled 57 meters along an angled hill with a force of 181 N, which elevates the man 28 meters above the bottom of the hill. The man then hops on his sled and slides from rest to the bottom of the hill back along his 57 meter path, during which a 165 N frictional force acts upon his sled. What is the velocity in mis of the man on the sled right as he reaches the bottom of the hill? QUESTION 8 4 points Save Answer A motor spins a disk (Idisk = 24.6 kg*m ) with a torque of 38 N'm, and a 19 N frictional force acts on the disk at a radius of 1.6 m. Attached to the disk at a radius of 1,8 m is a 3.1 kg mass. What is the moment of inertia of the system? Click Save and Submit to save and submit. Click Save All Answers to save all answers.
