(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

So the goal is to reach a distance H in the x-direction, starting from a height H in the y-direction, and you need to minimize the speed, and find the smalest and angle.

2. Relevant equations

i did:

dx = V cos(theta) *t and

y = y_0 +V sin(theta)*t-1/2*g*t^2

Vx = Vcos(theta) Vy = Vsin(theta)

3. The attempt at a solution

i set them equal to each other and solve for time

but I am not quite sure and the minimization part.

do I have to take the derivative with respect of theta and set it equal to 0?
