5. At some point in its orbit, assume that our asteroid is moving with the speed of 28.0 km/s

a. Determine the kinetic energy (KE) of the asteroid assuming it has a mass of 1500 kilograms. Be sure that your answer is in the correct units of energy. (1 kilometer = 1000 meters; 1 Joule = kgm2/sec2). Show all of your work.

b. By what factor would the KE change if the mass was doubled? Would the KE double, triple, or quadruple? Explain.

c. what factor would the KE change if the speed was doubled? Would the KE double, triple, or quadruple? Explain.
