An object with mass m1 has an initial velocity u1 = 3.0i m/s and collides elastically with another object of equal mass m2 = m at rest. After the collision, m1 moves at an angle θ1 = 30° with respect to its initial direction of motion. Using the center of mass frame, determine the velocity of both objects after the collision.
Two particles with masses m1 = 4 kg and m2 = 8 kg undergo an oblique central collision. After the collision, v1 = -6i + 5j - 8k and v2 = 7i - 10j + 6k. If the coefficient of restitution = 0.6, find the velocity of each particle before the collision.
