1. A projectile is launched at angle(theta) relative to the horizontal (see the figure below). The

initial height of the projectile above the surface of the table is h, and it hits the table at

distance (delta)x from the launch point. Find the launch speed vi of the projectile.

2. Relevant equations

(delta x)= Vi(initial velocity of x) + (delta t)

(delta y)=Vi(initial velocity of y)(delta t)-0.5g(delta t)^2

yi=yf (initial position equals final position)

3. The attempt at a solution

i think i have to some for some variable in one equation and then plug that into the other equation and solve for Vi(initial velocity)
