Question

Circular motion problems in relataded to angular velocity ouetion awesome

Answer 1

bead is given a small push at the top of a hoop (position A) and is constrained to slide

around a frictionless circular wire (in a vertical plane). Circle the arrow that best

describes the direction of the acceleration when the bead is at the position B.

Problem 1 Solution: The bead is speeding up at position B therefore it has a tangential

component of the acceleration (pointing downward) and it is traveling in a circular

trajectory so it has a radial component of the acceleration pointing towards the center of

the circle. Direction 4 best describes the sum of these two components.
