Jamal pulls a 200N sled up a 28° slope at a constant speed by a force of 100N. Near the top of the hill he releases the sled (the force F is removed)
a. Draw a free body diagrams for both cases: the sled moves up the slope and the sled moves down the slope. In both cases show all the forces and their components.
b. With what acceleration does the sled go down the slope?
