"Identify at least TEN different wheels in your home and/or in your community. At least THREE should be a wheel that is not associated with transportation. Ten wheels:
1.
2.
3
4.
5.
6.
7.
8.(not transport related)
9.(not transport related)
10. (not transport related)

For FIVE of them, do the following:

Measure or ESTIMATE the diameter (the distance from one edge to the opposite edge, going through the very center) of each wheel. *modification: you can estimate the diameter. If you do not have a ruler Use the length of your hand as a guide, or a dollar bill is = to 6.14 inches
Describe each wheel, its size, and its use.
Explain where the force comes from that causes the torque.

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
