Frequency, Amplitude, Mass
A spring of force constant 4.0 N/m oscillates with a period of 1.0 sec. with a particular mass m attached. A total energy of 0.130 J is put into the spring-mass system. What is the frequency of the motion? Find the amplitude of the motion. Find the value of the mass, m. What is the speed of the mass when its displacement is 15.0 cm?
