Homework Statement
In a circus act, clowns are shot from a cannon at a constant speed vo = 11.1 m/s. The angle of launch may be varied. What is the maximum distance D that a clown may travel, if the landing pad is at the same height as the mouth of the cannon?
Knowns:
Vo=11.1 m/s
x = 0
y = 0
V2=0
y2=0
Homework Equations
Vx= Vo*cos(theta)
Vy= Vo*sin(theta)
Δy= Vosin(theta)Δt + .5aΔt^2
The Attempt at a Solution
So I first solved for Δt,
Δy = 0 = (11.1)sin(theta) + (.5)(-9.8)Δt
Δt = (2(11.1)sin(theta))/9.8
Next I attempted to solve for Δx,
Δx = (11.1)cos(theta) * Δt
Substituting for Δt,
Δx = (11.1)cos(theta) * (2(11.1)sin(theta))/9.8
And I got lost D;!
