The small car that has a mass of 20 [kg] rolls freely on the horizontal track and carries the 5 [kg] sphere mounted on the light rotating rod with r = 0.4 [m]. A geared motor drive maintains a constant angular speed ω = 4 [rad/s] of the rod. If the car has a speed |v| = 0.6 [m/s] when θ = 0, calculate |v| when θ = 60◦ . Neglect the mass of the wheels and any friction.

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)
