How do you find how much time took a bullet to hit the ground?
Whatever the equation to find the last time when you know acceleration and everything you need to understand just how long it took the ball touches the ground? I need the quadratic formula
h (t) = h0 + v0 * t + (2.1) ^ 2 Plug the values you have for h0, v0, a. Then use the quadratic formula to solve for the zeros, ie, t such that h (t) = 0.

$2.79 Widespread Panic's eighth album is a rather grave and ponderous affair. Filled with hippie homilies and philosophical ruminations, it sounds more like Jefferson Airplane circa After Bathing At Baxter's than the Allman Brothers, with whom Panic is most often compared. They do include a few of their muscular jazz-tinged rambles, but more often they're intent on documenting their search for meaning. ... |
