Question

The data in the following table describe the initial and final positions of a moving car. The elapsed time for each of the three pairs of positions listed in the table is 0.46 s. Review the concept of average velocity in Section 2.2 and then determine the average velocity (magnitude and direction) for each of the three pairs. Note that the algebraic sign of your answers will convey the direction.

	Initial position x0	Final position x
(a)	+2.3 m	+6.1 m
(b)	+5.6 m	+2.5 m
(c)	-3.1 m	+7.1 m

(a) v =  ---Select--- - +    ---Select--- s m/s^2 m/s m

(b) v =  ---Select--- - +    ---Select--- m/s s m m/s^2

(c) v =  ---Select--- - +    ---Select--- m m/s m/s^2 s
