QUESTION 7 12 p 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 m/s of the man on the sled right as he reaches the bottom of the hill
