Long Problem (16pts) A mass is attached to a horizontal spring so that it can oscillate horizontally on a frictionless surface. The mass is 0.500 kg. The spring oscillates with a frequency of 3.00 Hz and has an amplitude of 0.850m. a) What is the angular velocity of the oscillation? b) What is the spring constant of the spring? c) What is the maximum velocity of the mass? d) What is the velocity of the mass when it is 0.400 m from equilibrium
