Homework Statement
A launcher is on top of a table and fire the projectile horizontally. The table/launcher height is 1.1 m and the projectile landed 3.2 m away from the table.
h=1.1 m
R=3.2 m
Find the velocity of the projectile as it leaves the launcher.
Homework Equations
tanθ=y/x
Δx = V(i)t + 1/2at^2
The Attempt at a Solution
θ = tan^-1(1.1/3.2) θ= 18.97°
After this I am lost. I assume I need the angle but I'm not sure for what.
I think I may need to solve for both x and y. My x and y values are (0,1.1) (3.2,0)
x = V(i)t ?
y = h -1/2gt^2 ?
Since I don't have t I don't what other equations I can use.
Please let me know if I am on the right track!
Thank you.
