8. A student rolls a marble alongside a meterstick to measure
its velocity. At t1 = -2.5 s, its position is x1 = 4.3 cm, and at
t2 = 4.5 s it is at x2 = 18.5 cm. Determine its average velocity
during this time interval.
9. The position of a ball rolling along a straight line is given by
? = 1.8−3.6? +1.5?2, where x is in meters and t is in seconds.
Determine the average velocity of the ball over the interval t =
1.0 s to 3.0 s. Determine the instantaneous velocity at t = 3.0
s.
10. A position vs time graph for an object moving in the y direction is shown. a. Determine the instantaneous velocity at t = 2.00 s by measuring the slope of the tangent line shown in the graph. b. For what value of t is the velocity zero?

So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...
