How fast would a hamster have to get a hamster wheel spinning so that it could ride around on the inside for a complete revolution?
Homework Answers
The minimum speed required can be calculated by considering the condition when the hamster is at the top of the spinning wheel, completely upside down. At that point there is gravitational force acting downwards and the centripetal force acting upwards. Let us say that the hamsters speed is v. Then we can write, (vertically the mass is at static equilibrium),
This is the minimum speed required by the hamster so the hamster is able to ride inside for a complete revolution. In rpm we can write this as,

A common amusement park ride is a Ferris wheel (see figure below, which is not drawn to scale). Riders sit in chairs that are on pivots so they remain level as the wheel turns at a constant rate.
A common amusement park ride is a Ferris wheel (see figure below, which is not drawn to scale). Riders sit in chairs that are on pivots so they remain level as the wheel turns at a constant rate. A particular Ferris wheel has a radius of 27 meters, and it makes one complete revolution around its axle (at location A) in 24 s. In all of the following questions, consider location A (at the center of the axle) as the...

How fast would two nuclei have to move so that in a head-on collision they would get close enough to fuse? (Treat the nuclei as point charges, and assume that a separation of 1.0 × 10-15 m is required for fusion.) Express your answer using two significant figures. Constants If two deuterium nuclei (charge +e, mass 3.34 x 10-27kg) get close enough together, the attraction of the strong nuclear force will fuse them to make an...

How fast (as a percentage of light speed) would a star have to be moving so that the frequency of the light we receive from it is 14.0 % higher than the frequency of the light it is emitting? Would it be moving away from us or toward us? (Assume it is moving either directly away from us or directly toward us.)

ONLY NEED ANSWER TO PART (A + B)
Some amusement parks have a double Ferris wheel, which consists of two vertically rotating wheels that are attached to each other by a bar that also rotates. There are eight gondolas equally spaced on each wheel. Riders experience a combination of two circular motions that provide a sensation more thrilling than the classic single Ferris wheel. In particular, riders experience the greatest sensation when their rate of change in height is the...
