I have a few questions to answer and I don't know how to start answering them.

1. On a position time graph, compare the instantaneous velocities of an object when the tangent to the curve slopes upward to the right, when the tangent slopes downward to the right, and when the tangent is horizontal.

2. After making a delivery, a truck driver must maneuver the vehicle backward down a narrow ramp. The speed of the truck increases with distance down the ramp. Describe the truck's acceleration.

3. Suppose an object starts from res. Explain how the displacement of the object, which has a constant acceleration, can be determined from a velocity time graph.
