    Projectile Motion (Angles of projection problem)

    Ah okay I didn't know that So if I leave the equation in the form: v^2 = vo^2 + 2ax I get: (-55sinθ - 32.174*(35/55cosθ))^2 = (55sinθ)^2 + 2*(-32.174)(-20) Which turns into: 419.2cos(θ)^2+2252.18cosθsinθ-1286.96 = 0 Also when I try using the equation x = x0 + v0t + 1/2at^2 I get a...

    Projectile Motion (Angles of projection problem)

    Thanks :) I see what I did wrong there, the vertical velocity is actually: v = -55sinθ1 + (-32.174)(35) / 55cosθ1 Therefore: v= v0 + sqrt(2ax) (-55sinθ1 + (-32.174)(35/55cosθ1)) = -55sinθ1 + sqrt(2(-32.174)(-20)) I'm still doing this for below the horizon though so when I do algebra for the...

    Projectile Motion (Angles of projection problem)

    Homework Statement The fireman wishes to direct the flow of water from his hose to the fire at B. Determine two possible angles θ1 and θ2 at which this can be done. Water flows from the hose at v = 55 ft/s. There is no air friction. Homework Equations v = v0 + at x = x0 + vt v2 = v^{2}_{0}...
