When I try to do a force system, it becomes very quickly very messy. I must be doing something wrongWe use an horizontal F force to push a 6kg sled at a constant speed on 4m to the top of a small hill angled at 30 degrees. If uc = 0.2, find the work done on the sled (a) by the F force; (b) by the gravity force; (c) by the friction force. (d) What is the total work done on the sled ?
The answers are: 179J, -118J, -61.4J, 0
