Example #1: Graph Velocity and Acceleration

For the curve in the following figure, find x as a function of t.

Henry hits a hockey puck in the positive x-direction at time, t ≈ t 0. The puck is then stopped by a net starting at time, t ≈ t1. Which of the following curves could describe the acceleration of the hockey puck if we ignore any effects of friction?

The graph in the figure describes the acceleration as a function of time for a stone rolling down a hill starting from rest. (a) Find the change in the stones velocity between t = 2.5 and t = 7.5. (b) Sketch a graph of the stones velocity as a function of time.

1. The slope at a point on a position-versus-time graph of an object isa. the object's speed at that point.b. the object's average velocity at that point.c. the object's instantaneous velocity at that point.d. the object's acceleration at that point.e. the distance traveled by the object to that point.2. The area under a velocity-versus-time graph of an object isa. the object's speed at that point.b. the object's acceleration at that point.c. the distance traveled by the object.d. the displacement of the object.3. Is it possible for an object's instantaneous velocity and instantaneous acceleration to be of opposite sign at some instant of time?a. Yes.b. No.c. Need more information

Consider the case when the constant A = 4. Plot the graph of y = 4/x.

An Olympic-class sprinter starts a race with an acceleration of 4.50 m/s2. (a) What is her speed 2.40 s later? (b) Sketch a graph of her position vs. time for this period.
