Part (a)Enter an expression that describes the vertical position, y(t)y(t), of one of the car tires as a function of time, tt, in terms of the defined quantities. Assume the motion is sinusoidal, with its argument in radians and the positive yy-axis up. Take the tire's equilibrium position as y=0y=0 and take y(0)=0y(0)=0 and increasing.
