The disk is horizontal and turns so that d theta/dt = ct about the vertical. Forces cause a marble to move in a slot such that its radial distance from the center equals kt^2. Note that c and k are constants. a. Find the acceleration of the marble. b. At what time does the radial acceleration vanish?
a carnot power cycle operates on 1.5 kg of air between the limits of 400 k and 250 k completing one cycle each second.
