A 25.0-g ice cube is set sliding around the cone without friction in a horizontal circle of radius R.
1. Draw a diagram, put in all forces, and pick an appropriate coordinate system.
2. Find the speed the ice cube must have as a function of R, g and α. Show all work and give all reasoning.
3. What speed would be required to repeat this situation but with R_new = 2R_old?
4. If the time to complete one orbit is T when the radius is R, what is the time to complete one orbit when the radius is 2R?

Many communication satellites are placed in a circular orbit around the Earth at a radius where the period (the time to go around the Earth once) is 24 hours. If the satellite is above some point on the equator, it stays above that point as the Earth rotates, so that as viewed from the rotating Earth the satellite appears to be motionless. That is why you see dish antennas pointing at a "fixed" point in space. (a) Calculate the radius...

Problem: Learning to fly In this example, we will apply conservation of energy, including potential energy, together with Newton’s laws and the expression for the acceleration in the radial direction of an object moving on a circular path. A young fledgling bird of mass m is sat at the very top of a dome, which is circular in cross section of radius R. Starting with an initial velocity of zero, the bird starts to slide down the dome. There is...

A thick walled cylinder has a light string
wrapped around its outer radius and rotates
about a horizontal axis. The string then goes
vertically straight up and over a massive
pulley that also rotates about a horizontal
axis, and finally connects to a mass m =
0.900 kg on a rough incline (μk = 0.200) that
is angled at 25.0° to the horizontal.
