At a time t after being projected from the ground, a projectile is displaced x units horizontally and y units vertically above its point of projection. (Use any variable or symbol stated above along with the following as necessary: g.)
(a) What are the horizontal and vertical components of the initial velocity of the projectile?

Answer: The horizontal component of the initial velocity of the projectile is (x/t) m/s and the vertical component is (y/t + gt) m/s. This is because the distance is x units horizontally after time t and the distance is y units vertically after time t, so the horizontal velocity is x/t and the vertical velocity is (y/t + gt) due to the acceleration of gravity of g m/s2.
