You are pulling a 20 kg sled up a snowy hill (no friction) by a rope. The angle of the hill is 10 degrees above the horizontal and the angle of the rope is 30 degrees with respect to the hill. You are pulling the sled with constant speed over a distance of 20 meters along the snowy surface of the hill. 1. What is the force you are applying with the rope on the sled during this pull? 2. How much work is done by that force over the distance you pull it? 3. If you let go of the rope at the 20-meter point, how fast will the sled be moving when it reaches the start again?

Question
You are pulling a 20 kg sled up a snowy hill (no friction) by a rope. The angle of the hill is 10
degrees above the horizontal and the angle of the rope is 30 degrees with respect to the hill. You
are pulling the sled with constant speed over a distance of 20 meters along the snowy surface of
the hill.
1. What is the force you are applying with the rope on the sled during this pull?
2. How much work is done by that force over the distance you pull it?
3. If you let go of the rope at the 20-meter point, how fast will the sled be moving when it
reaches the start again?
