PHeTMotionSimulation

This assignment requires you to use the University of Colorado simulations.  One way to access them is from the link on this page, or do a Google Search “Phet   .edu”  or copy this link directly into your browser.   http://phet.colorado.edu/simulations/sims.php?sim=The_Moving_Man

Also read the article titled “Basic Physics”, written by Richard Feynman, Nobel Prize winner, as the foreward to his textbook.  Write a 150 word reaction (not summary)  to the approach to physics that Mr. Feynman describes.

Page 55 of your lab book, Conservation of energy with rotational motion:

The following data was collect with a Vernier LabQuest and Ranefinder:

Radius of rotation  (flywheel radius) :  .100m

Hanging mass:  .200kg

Position change of the mass:  .243m

Final velocity of the mass:   .618m/s

Show the Energy balance:  delta PE mass = KEmass + KEflywheel

and give % error rel to delta P.E.

1. How far will an arrow go if launched horizontally at 20m/s from a height of 10m?

2. This same arrow is launched at a 30 degree angle from the ground.  Find the air-time, max height and range (hoiz. dist)

3. A football punt is in the air for 3.6 seconds and travels 40m.  What is the initial speed of the ball and the angle it leaves the kicker’s foot?

(Answers – 1:   28.6m, 1.43 sec   2:    2 sec, 5m high, 34m    3:  58deg, 21m/s
