Spacecrafts, P and Q, have been deployed to orbit around the center of the Earth. Spacecraft P is moving at an altitude of 5.50$\(\times\)$10³ km, while spacecraft Q is at an altitude of 10.8$\(\times\)$10³ km. Determine the kinetic energies of P and Q, if their mass is 2.00$\(\times\)$10³ kg each. Assume the orbits are circular.
Hint: gravitational constant G = 6.67$\(\times\)$10^-11 Nm²/kg², mass of earth M_E = 5.98$\(\times\)$10²⁴ kg, radius of earth = 6.38$\(\times\)$10⁶ m
