    If anyone could help me understand and answer this question that would be great!

    A ball of mass m is thrown of a cliff at an angle of π/4 to the horizontal with an initial speed of 20ms-1. Gravity -mgk acts on the ball as well as air resistance -2VBA(t), where VBA(t) is the velocity of the ball relative to the air. Wind blows with velocity relative to the ground at 2j

    Obtain three differential equations describing the evolution in the particles velocity.
