Compute all parts of given question:
Question: A loaded penguin sled weighing 80.5 N rests on a plane inclined at angle = 18.3° to the horizontal. Between the sled and the plane, the coefficient of static friction is 0.280, and the coefficient of kinetic friction is 0.160.
Part A: What is the least magnitude of the force, parallel to the plane, that will prevent the sled from slipping down the plane?
Part B: What is the minimum magnitude force that will start the sled moving up the plane?
Part C: What value of force is required to move the sled up the plane at constant velocity?
Please help for the above question, completely confused!! Show each steps if possible, Thanks.
