Two seconds after projection, the particle has moved $30\text{ m}$ horizontally and is at its maximum height above the ground. Determine the initial speed and the angle of projection of the particle.
This 5-mark question has a full step-by-step worked solution and mark scheme. One marking point: “Apply vertical motion up to the greatest height to get $V\sin\theta = 2g\;(=20)$” …
