Question 4 of 12 < View Policies Show Attempt History Current Attempt in Progress In a binary star system, Star 1 has a mass 2 x 100 kg. and Star 2 has a mass 1 x 10 kg. At a certain instant (r= 0), Star 1 is at the origin with zero velocity, and Star 2 is at (-1.50 x 10",0,0) m with a velocity (0.-3.50 x 10.0) m/s. Later, at r = 4.5 x 10° s. Star 1 has a velocity (-1.12453 x 10.-6.76443 x 10³.0) m/s. Define the system as Star 1 and Star 2. It is an isolated system. Part 1 Atr= 0, what is the total kinetic energy of the system? Kutal = Hint Part 2 Your answer is correct. Kras 6.125E38 Your answer is incorrect. Atr= 0, what is the translational kinetic energy of the system? i 3.75E51 0.14/1 E Hint The translational kinetic energy is associated with the center of mass motion.

Part 3 * Your answer is incorrect. Atr= 0, what is the relative kinetic energy of the system? Krel= Hint Save for Later Part 4 The total kinetic energy can be subdivided into two parts: translational kinetic energy and relative kinetic energy. Kot Atr= 4.5 x 10 s, what is the total kinetic energy of the system? Save for Later Part 5 -3.75E51 J Ktrans = Att 4.5 x 10° s, what is the translational kinetic energy of the system?
