Hi, I have a few questions, thanks for any help you can give! 1. If a wheel is rotating at a rate of 3.1 revolutions every 3.6 seconds. Through what angle, in radians, does the wheel rotate in 1 second?? 2. A car can negotiate an unbanked curve safely at a certain maximum speed when the...

Just need to know if I'm on the right track (again): A wheel of mass M has radius R. It is standing vertically on the floor, and we want to exert a horizontal force F at its axle so that it will climb a step against which it rests. The step has height h, where h < R. What minimum force F is...

A person stadns on a platform, initially at rest, that can rotate freely without friction. The moment of inertia of the person plus the platform is I_p. The person holds a spinning bicycle wheel with axis horizontal. The wheel has momemnt of inertia I_w and angular velocity \omega_w. What will...

A person in a wheel chair is moving up a ramp at a constant speed. Their total weight is 900N. The ramp makes an angle of 10degrees to the horizon. Calculate the force required to keep the wheel chair moving at constant speed up the ramp. (You may ignore the effects of friction) The ramp...

I can't find formula for determing the number of rotations a wheel makes in one minute. Diameter = 26" Traveling at 20 feet per second. is there a formula for RPM? Also need the formula to determine angular velocity. thanks

i've been doing some physics problems out of the text and I was wondering: If an electric fan were to be turned off and you knew its angular acceleration, it is possible to find the number of revolutions it makes in a certain time interval? also, i having a difficult time with this...

My car has a knob on the radio to control the volume. How would I make another volume control sp that I could put by the steering wheel so I don't have to reach for the knob on the radio?

what minimum horizontal force is needed to pull a wheel of radius R and mass M over a step of height H. force is supplied at center of wheel. ?

Its been over 4 years since physics, I'm a little rusty. I am doing a cg animation of a car moving, and I can't get the wheels to look right when turning(I'm eyeballing the rotation of the wheels). The wheels look like they are turning to slow or too fast. 1)How do you determine how long...

Problem 3. A potter's wheel of radius 0.19m and mas 82.10 kg is freely rotating at 46.0 rev/min. The potter can stop the wheel in 8.4 s by pressing a wet rag against the rim a. What is the angular acceleration of the wheel? In rad/s^2. Note: Is the formula to use in this problem...

Ferris Wheel ...Trick Question? This is one of those that might be a typo or I am really missing something. A 250lb student is riding on a steadily rotating Ferris Wheel. If the student has an apparent weight of 250lb at the top what will be the students apparent weight at the bottom? What...

The problems reads, A carnival Ferris wheel has a 14.2m radius and completes one revolution about its horizontal axis in 10.1s. Consider the time interval from the instant when a passenger is at the lowest point of the uniform circular motion to a clock reading 5.05 seconds later. What was the...

How many revolutions per minute would a 15m diameter Ferris wheel need to make for the passengers to feel weightless at the topmost point?

Wheel size and speed help! Okay, my father and I have been an argument for days on this. We were arguing about wheel sizes and their effected distance traveled. A larger wheel has a greater circumference; therefore one revolution will travel a farther distance. Here's the argument. If you have...
