In the first question, we have a small bead set into motion within a smooth conical cone and making a horizontal motion. If the bead is moving with a centripetal acceleration of g, what is the angle of the cone to the vertical?

In the second question, we have a 1.2m long pendulum making a horizontal circular motion. Find the speed of the attached mass.

In the third question, we have persons standing on a certain latitude and equator. If the centripetal acceleration of the person at the latitude is 1/3 of the one at the equator, find the latitude.
