Question 3 (12 points) A 0.60 kg mass at the end of a spring vibrates 3.0 times per second with an amplitude of 0. 13 m. Determine: a) the total energy of the system b) the velocity at the equilibrium point c) the velocity when it's 0.10 m away from the equilibrium point. Note: use k = 30.0 N/m if unable to find this and deduct 3 marks. (6, 3, 3 marks)
