Page |2 3. A marathoner runs due east for 61.5% of the time, stops and rests for 6.5% of the time, and then runs due west for remainder of the time. The average eastward velocity has magnitude 12.5 miles/hour while the average westward velocity has a magnitude of 11.0 miles per hour. Find (a) the average speed, and (b) the average velocity for the entire race. (c) How far did he run for a total time 2 hours 20 min...

Flanders is an exceptional runner. Usually, the more he runs, the better he feels. However, he hits a “wall” after running for two hours. That is, once he runs for two hours, additional time spent running makes him worse off. After three hours of running he gets a “second wind” and running becomes enjoyable again. Flanders has eight free hours a day. Draw Flanders’s budget line between hours spent running (measured on the horizontal axis) and hours spent on other...

Some chipmunks are running back and forth along a tree branch. One chipmunk is at rest at t = 0 s and starts running to the right. It speeds up to a speed of 1.5 m/s in 3 s. How far does it run in this time? Another chipmunk starts from rest and runs to the left. It speeds up to a speed of 2.1 m/s in 3.2 s. It then slows to a stop in...

Question 1 (1 point) A train running along a straight track at 73 m/s is slowed uniformly to a stop in 10.6 s. Find the stopping distance. Question 2 (1 point) In the first part of your trip, you drive 55 miles at an average speed of 53 miles/hour. In the second part of your trip, you drive 5 hours at an average speed of 67 miles/hour. What is average speed during your whole trip? Question 3 (1 point) A...

Write a program that calculates the calories burned while running over a given number of miles. While several factors determine how many calories are burned during a mile run, for this program, 90 calories are burned for every mile of running. The cumulative calories burned during a run can be calculated as: Calories * Distance For example, if a person runs 5 miles, the total calories burned is 450. After 3 hours, the person has burned 2 calories. The program...

1. A car traveling at a speed of vo = 52 m/s stops smoothly (that is, its deceleration is constant) over a distance of d = 147 m. After the car has gone 1/3 of the stopping distance, what is its speed? v1/3 = 2. An athlete sprinter 50m in 9.3 seconds, and then walks slowly back to the starting line in total time of 58 seconds. (Assume he runs in the positive direction.) What is his average walking velocity? vav...

A turtle and bunny have a race. Running a straight line of 42km. 1. What is the average speed of the turtle knowing that it will take him 6 hours to run it? 2. The bunny will obviously be faster, being able to run 10 km/hr. How long will it take him to run it? 3. If the bunny gives the turtle a 1 hr head start, how far will the turtle get? 4. If the bunny gives the turtle...

POGIL Kinematic in one dimension o-meter run (approximately 3.1 mi or 16,404 ft) is a common long-distance ru the World the 5000 Dibab nning event in track and field. It is one of the track events in the Olympic Games and hampionships in Athletics, run over 12.5 laps. The official world records in by Kenenisa Bekele with 12:37minutes for men and Tirunesh meters are held a with 14:11 minutes for women. Both are from Bekoji. Ethiopia. 1. If after the...

Bruce runs a 100m race. 5 seconds after the race
started Bruce is 45 mi from the starting line and reaches his max
speed, he runs at his max speed for the rest of the race. Bryce
notices that he is 77 meters from the starting line 9 seconds after
the race started.
a. what is Bryce's max speed
b. suppose Bryce runs for an additional Z seconds
after reaching his max speed
