Okay so: Amir pitched a baseball at an initial height of 5.9 feet with a velocity of 73.16 feet per second. About how long will it take the ball Amir pitched to hit the ground? 4.66 secs 2.94 secs 2.35 secs 1.47 secs

factor away :)

Oh ok... Thanks :) also when you get the final product which will be in t = ? OR t = ? which one will it be?

initial velocity formula, which is what you'd be using for this \(\huge h = -16t^2+vt+h_o\) you'd be solving for "t", you have "v" and when the ball hits the ground h = 0 so, just solve the quadratic :)

just a plain quadratic formula matter

ohh and \(h_o = 5.9\)

Wait, but isn't (t) just the time in which the projectile will hit it's max point?
jdoe0001
  • jdoe0001
hmm, that's "t" at the parabola vertex point "t" at the ground level, would be when y =0

So..... \[0 = -16x^{2} + 73.16 + 5.9\]
jdoe0001
  • jdoe0001
\(0 = -16x^{2} + 73.16x + 5.9\)

Oh yes right lol, so that's what I would use and I would factor right?
jdoe0001
  • jdoe0001
yes, you'd get 2 values, one will be extraneous or won't apply, and that'd be it :)
