Question: An object of mass 5.13kg moves on a horizontal surface without friction under the influence of a spring with constant 9.88 N/cm. The object is displaced 53.5 cm from the equilibrium position of the spring and is given an initial velocity of 11.2 m/s with time 0.
Part A: Write the equations of the position, velocity and acceleration of the oscillator as a function of time.
Express your knowledge to solve the above question.
