A ball of mass 0.250 kg is attached to a spring with spring constant 35.0 N/m and relaxed length 0.200 m. The other end of the spring is attached to a vertical pole. The ball is set into circular motion in the horizontal plane with the spring making an angle 25degrees with the pole.
a) find the length of the spring during this motion.
b) find the velocity of the ball during this motion.
The Attempt at a Solution
I have set it up to find v, but am stuck on how to find x. Thank you very much.
