be the initial speed (m/s), so that 
(also m/s) is the vertical component of the initial velocity vector.
are the initial and final velocities, 
is the acceleration, and 
is the vertical displacement. At its maximum height (which the question seems to say occurs after 4 seconds), the velocity is 0, and throughout its motion the projectile is under the influence of gravity so that
