Atexas cockroach of mass 0.117 kg runs counterclockwise around the rim of a lazy susan (a circular disk mounted on a vertical axle) that has a radius 17.3 cm, rotational inertia 5.20 x 10-3 kg·m2, and frictionless bearings. the cockroach's speed (relative to the ground) is 1.91 m/s, and the lazy susan turns clockwise with angular velocity ω0 = 2.87 rad/s. the cockroach finds a bread crumb on the rim and, of course, stops. (a) what is the angular speed of the lazy susan after the cockroach stops? (b) is mechanical energy conserved as it stops?

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
