1) A cyclist rides around a circle track with a constant speed of 8 m/s. If the radius of the track is 150 m then what acceleration does it experience?
2) A 75 kg tightrope walker is in the middle of the rope. The tightrope sags in the middle and creates a 30 degree angle below the horizontal. What is the tension in the cable?
3) A 0.75 kg yo-yo is spun around at a constant speed in a circle. The circle has a radius of 1.255 m. If one revolution takes 0.5 seconds, find the angular speed and centripetal force.

A cyclist starts from rest and rides in a straight line, increasing speed so that her wheels have a constant angular acceleration of 2.0 rad/s2 around their axles. She accelerates until her wheels are rotating at 8.0 rad/s. If the radius of a tire is 0.31 meters, how far has the cyclist traveled? Answer in m (#10.9.5)
