A 0.500 kg sphere moving with a velocity (2.00i - 3.50j + 1.00k) m/s strikes another sphere of mass 1.50 kg moving with a velocity (-1.00i + 2.00j - 2.80k) m/s.
(a) If the velocity of the 0.500 kg sphere after the collision is (-1.00i + 3.00j - 8.00k) m/s, find the velocity of the 1.50 kg sphere and identify the kind of collision (elastic, inelastic, or perfectly inelastic).
( 0 i + ___ j + ___k)m/s
so far for i, guess zero and it was correct. so i am tryna figure whats the j and k :)
