Homework Statement
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.
Homework 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)
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)
