A stone with mass m = 8 g at the end of a massless cord is swaying in a circle of radius R = 1.76 m with and angular velocity ω = 1 rad/s.

1. Write an expression for the velocity v of the stone.
2. In order to travel in a circle, the direction the stones path must constantly be changing (curving inward). This constant change in direction towards the center of the circle is a center pointing acceleration called centripetal acceleration ac. Write an expression for the centripetal acceleration ac of the stone, in terms of the linear velocity.
