4 pt An object with a mass of m= 1.27 kg connected to a spring oscillates on a horizontal frictionless surface as shown in the figure. Simple harmonic oscill: X(t) = A cos(wt) The equation of the motion of the mass is given by r = 0.319 cos(1.011) where the position is measured in meters, the time t is measured in seconds. Determine the total mechanical energy of the mass spring oscillator. (in J)
