At its highest point, the mass is 12 cm from the floor, and at its lowest point, the mass is 6 cm from the floor. At t = 0, the mass is at its equilibrium and moving downwards, and a single period takes 0.5 seconds. HINT: Graph your y(t) to check your answers. (a) Find a formula for y(t), the position of the mass from the floor as a function of time. (b) What is the position, velocity, and acceleration of the object at t = 2? (c) In its first period, during what time interval(s) is the speed, |v|, of the mass less than 1 cm/s?

An automobile with a mass of 1000 kg, including passengers, settles 1.0 cm closer to the road for every additional 100 kg of passengers. It is driven with a constant horizontal component of speed 20 km/h over a washboard road with sinusoidal bumps. The amplitude and wavelength of the sine curve are 5.0 cm and 20 cm, respectively.
