14. [-/10 Points] DETAILS ASK YOUR TEACHER A spacecraft consists of four rocket thrusters placed at equal distances around the equatorial line of a large sphere (as shown). The main spherical body of the craft has a radius of 15.0 m and a mass of 1.15 x 105 kg. Each rocket has a mass of 230 kg. In order to simulate gravity for the crew inside the craft, engineers calculate that the craft must be rotating with an angular velocity of 8.3 rad/s. The spacecraft is moving directly away from earth with a linear speed of 170 m/s. Determine the total kinetic energy of the craft. KEtotal = Later in the spacecraft's mission the thrusters will be extended on support arms until they are 20 m away from the edge of the sphere. Using angular momentum conservation, determine the new rotational speed of the craft in revolutions per minute. Assume the support arms have negligible mass. @new = rev/min
