2.| A man rides a bike along a straight road for 5 min, then has a at tire. He stops for 5 min to repair the at but can't x it. He walks the rest of the way, which takes him another 10 min. Use the particle model to draw a motion diagram of the man for the entire motion described here. Number the dots in order, starting with zero. 9.| Foraging bees often move in straight lines away from and toward their hives. Suppose a bee starts at its hive and ies 500 m due east, then ies 400 m west, then 700 m east. How far is the bee from the hive? 12.\" Figure P1.12 shows the motion diagram for a horse galloping in one direction along a straight path. Not every dot is labeled, but the dots are at equally spaced instants of time. What is the horse's velocity a. During the rst 10 seconds of its gallop? b. During the interval from 30 s to 40 s? 0. During the interval from 50 s to 70 s? 705 505 30s 10s FIGURE P1.12 50 150 250 350 450 550 650 22.\" If you make multiple measurements of your height, you are likely to nd that the results vary by nearly half an inch in either direction due to measurement error and actual variations in height, you are slightly shorter in the evening after gravity has compressed and reshaped your spine over the course of a day, One measurement of a man's height is 6 feet ad 1 inch. Express his height in meters, using the appropriate number of signicant gures. I 43. H In a typical greyhound race, a dog accelerates to a speed of 20 m/s over a distance of 30 In. It then maintains this speed. What would be a greyhound's time in the 100 m dashes? 7S||| John walks 1.00 km north, then turns right and walks 1.00 km east. His speed is 1.50 m/s during the entire stroll. a. What is the magnitude of his displacement, from beginning to end? b. If Jane starts at the same time and place as John, but walks in a straight line to the endpoint of J ohn's stroll, at what speed should she walk to arrive at the endpoint just when John does
