If a Projectile (Such as a Bullet)is Fired into the Air

If a projectile (such as a bullet) is fired into the air with an initial velocity v at an angle of elevation θ  (see the figure) , then the height h of the projectile at time t is given by h = -16 t ² + vt sin  θ Give the equation for the height, if v is 1,600 feet per second and θ  is 30°.
