Problems 49 through 52 show a partial motion diagram. For each: a. Complete the motion diagram by adding acceleration vectors. b. Write a physics problem for which this is the correct motion diagram. Be imaginative! Don’t forget to include enough information to make the problem complete and to state clearly what is to be found. c. Draw a pictorial representation for your problem. 49 FIGURE P1.49 50 FIGURE P1.50 51 FIGURE P1.51 52 FIGURE P1.52

Alex goes cruising on his dirtbike. He rides 7 km north, 3 km east, 4 km north, 6 km west, 12 km south, 3 km east, and finally 1 km north. What is Alex's displacement?
A. 12 km
B. 0 km
A car goes 78 m to the righty and then 22 m to the left. It makes this trip on 35 seconds.
a. What is the displacement in meters?
b. What is the total distance travelled in meters?
c. What is the average velocity?
d. What is the average speed in m/s?
A motorist drives north for 32.0 minutes at 80.5 km/h and then stops for 15.0 minutes. He then continues north, traveling 130 km in 1.80 h.
(a) What is his total displacement?
