Homework Statement
i have a problem from an in class lab where i have to find the initial velocity of the ball. given is the horizontal and vertical displacement of the projectile.
Dy(height)=100cm
Dx(range)=200m
0(theta)= 15degrees.
Find the initial velocity.
Homework Equations
not sure what equation to start with
The Attempt at a Solution
x-comp:
Vx1=Vo cos 60
y-comp:
Vy1=Vo sin 60
t=200/Vo cos 60
-100=Vo sin 60(200/Vo cos 60) + 1/2(-9.8)(200/Vo cos 60)^2
Vo= 2 numbers that make no sense
