A body P of mass 1.5 kg, travelling along the positive x-axis with speed 4.5 m/s, collides with another body Q of mass 3.2 kg which is initially at rest. As a result of the collision, P is deflected and moves with a speed 2.1 m/s in a direction which is at angle 30° below the x-axis. Q is set in motion at an angle 0 above the x-axis. Calculate the velocity and direction of Q after the collision. Vector a = 3i + 5j – 2k and vector 5 = -3j + 6k. Find a vector e such that 2a + 7b + 4c = 0
