During a snowball fight two balls with masses of 0.5 kg with a velocity of 20 m/s and 0.8 kg with a velocity of 25 m/s are thrown at each other in such a manner that they meet head-on and combine to form a single mass. If the direction of motion of the 0.5 km is considered +, What is the velocity of the combined mass and the amount of energy loss in the collision? A) zero B) -9.0 m/s, +210J C) +7.6 m/s, -350J D) + 9.0 m/s, -77 J E) -7.7 m/s, -273 J
