Concept explainers
A woman starts from her house and begins jogging down her street. In order to keep a record of her workout, she carries a stopwatch and records the time it takes her to reach specific landmarks such as intersections, school grounds, and churches. Since she knows the distance to each of these landmarks, she is able to tabulate the data shown here:
Time | Distance jogged |
10 min | 2.1 km |
17 min | 3.2km |
32 min | 6.5 km |
44 min | 8.6km |
Make a plot of the distance jogged versus time. Draw a test-fit me through the data, and use this line to estimate (a)the speed at which she was jogging in m/s and (b) the distance she will jog in 1 hour.

Determine the average velocity of the train in meters per second (m/s). [conversions: 1 km = 1000 m, 1 hr = 3600 s, 1 min = 60 sarrow_forward
- a person walks for 1.00 hr at a speed of 2.00 mi/hr. he stops for 1.00 hr. he then starts walking again and covers 2.00 mi at a speed of 1 mi/hr. find the average speed of the trip answer with Correct number of significant digitsarrow_forwardA cheetah was observed running at a speed of 27.4 m/s. Use the following facts to convert this speed to kilometers per hour (km/h). 1 km = 1000 m1 min = 60 sec1 hour = 60 minarrow_forwardBill runs at a steady pace of 5.00 m/s. How long will it take Bill to run 1.00 mile? (N.B. 1 mile =5280 feet). Answer in seconds.arrow_forward
- In a 3-lap auto race, the displacements and each time of the laps were recorded: • 1st lap: Ran from 0m to 34.5m in a time of 0s to 4.5s. • 2nd lap: Ran from 34.5m to 78.3m in a time of 4.5s to 9.2s. • 3rd lap: Ran from 78.3 m to 152.4 m in a time of 9.2 sec to 12.9 sec. Determine the speed of each lap and describe the “general” type of movement of the competition.arrow_forwardA man is running around a circular track that is 200 m in circumference. An observer uses a stopwatch to record the runner's time at the end of each lap, obtaining the data in the following table.

(Round your answer to two decimal places.) m/s(b) What was the man's average speed between 235 s and 351 s? (Round your answer to two decimal places.) m/s(c) Calculate the man's speed for each lap. Is he slowing down, speeding up, or neither? slowing downspeeding uparrow_forwardWhile driving on the highway at 100 km/hr, a billboard distracts you for 2.5 seconds.

Draw a smooth curve through the plotted points. By measuring the slope of your curve, find the instantaneous acceleration at t = 6 s, 18 s, and 25 s.arrow_forwardA bee flies from a petunia to a marigold at an average speed of 3 feet per second. Immediately upon reaching the marigold the bee turns around and flies back to the petunia at an average speed of 6 feet per second, following his original path.
