An object oscillates with an angular frequency = 6 rad/s. At t=0, the object is at xo = 6.5 cm. It is moving with velocity vx0 = 14 cm/s in the positive x-direction. The position of the object can be described through the equation x(t) = A cos(cot + 9). What is the the phase constant of the oscillation in radians? (Caution: If you are using the trig functions in the palette below, be careful to adjust the setting between degrees and radians as needed.) Calculate the value of the amplitude A of the oscillation in cm.
