some eggs are placed in a basket. the basket is safely rotated in a vertical plane so that the eggs describe a circle of radius 1 metre. what is the least speed at the top of the circle at which the eggs must move? the ans is 3.2m/s in this question, i managed to determine the forces present...the weight, centripetal force, i know i am suppose to form 2 equations and solve it, but i have absolutely no idea how to do it... i could only obtain one eqn: mv*2/r=mg-reaction (at the top of the rotation) at the bottom it would simply be mv*2/r=reaction-mg but how do you solve this and obtain the least speed? are there any other eqn?
