SHORTANSWER.Writethewordorphrasethatbestcompleteseachstatementoranswersthequestion.21)A cat runs along a straight line (thex-axis) from pointAto pointBto pointas shown in the figure. The distance between pointsAandCis 5.00 m, thedistance between pointsBandCis 10.0 m, and the positive direction of thex-axis points to the right. The time to run fromAtoBis 20.0 s, and the timefromBtoCis 8.00 s. As the cat runs along thex-axis between pointsAand(a) what is the magnitude of its average velocity?(b) what is its average speed?C,C21)
22)The figure shows the position of an object as a function of time. During thetime interval from timet= 0.0 s and timet= 9.0 s(a) what is the length of the path the object followed?(b) what is the displacement of the object?22)

23)As part of an exercise program, a woman walks south at a speed of 2.00 m/s for60.0 minutes. She then turns around and walks north a distance 3000 m in 25.0minutes(a) What is the woman's average velocity during her entire motion?23)
(b) What is the woman's average speed during her entire motion?
24)The figure shows the position of an object as a function of time, with allnumbers accurate to two significant figures. Between timet= 0.0 s and timet= 9.0 s(a) what is the average speed of the object?
