3) division is one unit. An object's (one dimensional) motion is represented by the following graph. Each x (meters) (4.5, 3) (6, 1.5) (0,0) t (s) (3,-1) a) Find the velocity of the object at t = 2.2 s. а) mag. dir. b) Find the position of the object at t = 4.3 s. b) mag. dir. c) What is the total distance traveled for the entire 6 second journey? c) d) What is the average velocity from t = 1.5 s to t= 4.5 s ? d) mag. dir. e) What is the average speed from t = 4 s to t = 6 s ?

1#2 Chapter 2 - The Derivative Function 89 The distance a person can walk in time t is given by d =vt where d is measured in miles and t is measured in hours. %3D a) Find the average velocity from t= 1 tot=4 hours. b) Estimate the person's velocity at t = 4 hours. A ball is dropped from a tall building and d is the number of feet it falls in t seconds. The following table shows some of the values of t and d. t (sec) 1 3. 4. 0. 0. d (ft) 15.07 57.90 | 127.03 201.76 |333.00 a) Plot the six data points. Label the axes and indicate the units that are being used. b) The slope of any secant line on the graph is a measure of velocity. Why? of the follin g bell ot t c) Make throo a

2. We are given the velocity funtion of mouing car Along an east-wed4 highung is V(4) = 3€²-24 where t- hours afterho and distance is measured east is the positive direction, in miles, Note that going A If st) is the position in miles from Norton Tewn Mall and at 1 pm the car was at Norton Town Hall, find S(4) B) What was the average velocity of the car from Zpm to 5 pm!

On a fishing trip on Lesser Slave Lake you drive your motorboat north at 20.0 km/h for 30.0 minutes. After realizing that you passed your fishing spot, you turn south and travel at 35 hm/h for 10.0 minutes. Determine your average. a) speed for this trip. [24km/h] b) velocity for this trip. [ 6.3 hm/h, North]
