A person thought it would be a good idea to change a tire on the side of a hill. The tire has a width
of W = 0.30 m and a radius of R = 0.40 m. The inside of the wheel is empty, but the wheel is solid
from a radius of R/2 to R with uniform density. The density of the material is 2000 kg/m3
(a) What is the mass, weight and moment of inertia of the wheel?
(b) If the wheel starts from rest and rolls down a 4.00 m ramp, 30.0
relative to the horizontal, what
is the wheel’s speed at the bottom of the ramp?
(c) What average torque do you need to apply to stop it at the bottom of the ramp in one revolution?

the demand for a certain type of auto tire is given by x=f(p) 50(1+e^-p/60). a)if the weekly quantity demanded is 60000 tires find the price? b)if the current price is $120 per tire and is increasing at a rate of $2 per week, what
There is a slow leak in your bike tire. The average rate of change of air in your tire is -2 pounds per square inch per day. The amount of air in your tire is now 70 pounds per sqsquare inch. Find the amount of air that will be in
The warranty on a new tire says that an automobile can travel for a distance of 92,000km before the tire wears out. The radius of the tire is 0.33m. How many revolutions does the tire make before wearing out? hello CJ I think we
I mean seeing professors to get help. Yes. Frankly I think it is a good idea to go to each one and introduce yourself if you have not done so. A very short social visit (short meaning a couple of minutes). Now for help. Yes go see

How did Darwin and Lamarck differ in their thinking about change in species? Darwin thought that organisms could induce their own changes, while Lamarck thought that change could only be induced by an organism’s environment.
