2) A mass of 2 kg is suspended from a spring with a known constant of 10 Newton per centimetre and allowed to come to rest. It is then set in motion by giving it an initial velocity of 120 centimetres per second. The equation for the system is given as x(t) = C, cos v5 t+ C2sinV5t Where x(t) is the displacement from the equilibrium position and t is the time in seconds. The angular frequency w = v5 cycles per second. Find: a. The constants Ci and C2 and the equation for the velocity of the mass.
