A horizontal block spring oscillator of mass 15 kg on a frictionless table and spring constant k is pulled 3 m to the right and released; after 0.1 seconds the block just passes the equilibrium position.

a) Find at t= 1 second the angular frequency, frequency, period, position, velocity, acceleration, and force on the block.

b) Draw the velocity function of the block over two periods.
