A. A disk of radius 0.15 m spins at a rate of18 rad/s. What is the linear speed of a point on its outer rim? Howlong does it take that point to make a complete revolution? Whatwould be given as the frequency in hertz of this motion?
B. A mass and spring system is built with aspring constant of 5.0 N/m and a mass of 2 kg. What is its periodof oscillation? What length would a simple pendulum have to have tomake an identical mass oscillate with that same period?
