While rowing across a lake, John does 3960 ft-lbs of work over 120 ft. How much force is John using?

Answers

Answer 1

66W. Explanation: Formula of Power: Worktimetaken. Given: Work = 3960J and time taken = 60.0s. Using the formula: Worktimetaken. = 3960J60.0s. = 66W.

Biomechanics informs runners on the best form for the greatest speed and lowest risk of injury. There are several websites and videos dedicated to instructing runners how to run effectively with correct biomechanics.

For this project, you are to measure and compare running speed using proper biomechanics versus running speed while not using proper biomechanics. Present your findings in a 300 word paper.

The experiment: Measure a 100-meter straight line. Research the biomechanics of running.

1st Attempt: Either you or another individual run the 100-meter as fast as possible without applying biomechanics. Have someone time this run using a timer or stopwatch.

2nd Attempt: The same person runs the 100 meters as fast as possible, applying the biomechanics information provided from one of the websites above or one you find on your own. Have someone time this run using a timer or stopwatch.

Equipment needed: stopwatch or timer

Your paper should include:
a title;
information on the biomechanics of running;
results of the experiment (timed run with and without applying biomechanics information);
discussion of the results of your experiment;
what elements of STEM were applied to improve running;
at least 300 words.
a reference page.
Your project should be:

well-organized;
contain appropriate language;
contain proper grammar, punctuation, and spelling;
contain information from credible sources;
contain a reference page listing all sources used for the assignment.

Answer:

i cant help sorry

Explanation:

Answer:

Today we are doing a project on biomechanics. For this project we are going to use stem variables with running to test the difference in this project.Biomechanics is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole organisms to organs, cells and cell organelles, using the methods of mechanics. The objective of this assignment is to record someone running 100 m and recording another person running the same distance but with another variable. I'm kind of thinking that the second person would wear leg weights for the second 100 m but that is just a thought.

So the first part is measuring the 100m test. It  was not that hard and it did take a little time but in the end we got it from the start of my  block to the middle of the block. After measuring then came the second step : thinking of the variable for the second person. So when i thought about this for the first time i did not think what variable to add and then when i actually thought that i could make this a little harder on the second person just for the test and a little fun and decided that the second person was going to wear leg weights while running the 100 m. after that i got a stopwatch and two friends to do this project for me.  The faster friend had leg weights and the slower friend did not have any.i did this to improve the slower friend  I told the first person that he was going to run 100 m. after that he started running and I recorded the time. It was 28 seconds. Then i told the second friend to also run the 100m but i also told him that he was going to wear leg weights. After that it took him a long 35 seconds including breaks to finish his 100 m.

List 6 different mechanisms in the Rube Goldberg cartoon and predict the
purpose of each. Does the mechanism change speed, force, torque, direction,
or type of movement?

Answers

Answer:

The mechanism change speed, force, torque, direction,  or type of movement is described below in detailed explanation.

Explanation:

A train that runs on a gearbox system is a mechanism employed for motion. The movement of the gears is transferred inside the teeth. Three or some extra gears are coordinated to produce a train with a gearbox system. When you want to take your train to the hilly areas, you utilize a gear train that produces more torque (conversion energy) but, reciprocal it for, less speed.

Answers

B, tech b only, Blow by is describe or defined as air going by the compression rings. Hope it helps

B only, is right technician A says the engine could have a cracked flywheel. Technician B says the compression rings could be worn. Thus, option (b) is correct.

What is technician?

A Technician installs, inspects, repairs, or changes complex systems, or performs diagnostic or structural tests. IT Technicians, Lab Technicians, Automotive Engineers, Laboratory Staff, Service Technicians, Clinical Pharmacists, and Dental Engineers are all examples of engineers.

Both technicians agreed that it was because of the differences in the objects. The engine can have a fractured flywheel if the A is being worked on. The compression rings, as the first B, might be worn. The expert was the circles on the pressed.

Therefore, option (b) is correct.
