Question

A projectile is fired horizontally with a velocity u so that it's trajectory of a parabola also often a expression for it time of flight and horizontal range

Answer 1

Answer:

Parabola Equation

The general equation of a parabola is: y = a(x-h)2 + k or x = a(y-k)2 +h, where (h,k) denotes the vertex. The standard equation of a regular parabola is y2 = 4ax.

Explanation:

How to find a parabola's equation using its Vertex Form

Step 1: use the (known) coordinates of the vertex, (h,k), to write the parabola's equation in the form: y=a(x−h)2+k. ...

Step 2: find the value of the coefficient a by substituting the coordinates of point P into the equation written in step 1 and solving for a.
