A projectile at ground level is fired at an angle (0 degrees < < 90 degrees) from the horizontal with an initial velocity

A projectile at ground level is fired at an angle Θ (0 degrees < Θ < 90 degrees) from the horizontal with an initial velocity “4gt”. Using the definition of gravitational acceleration “g”, derive an expression for the elevation y from the ground as a function of time t and angle Θ, assuming air resistance is neglected.
