during a volcano eruption a small piece of ash ejected from the volcano with an initial velocity of 368ft/sec. The height, H, in feeet of the ash projectile is given by the equation H=-16t square + 368t. Where t is the time in sec. The graph of this equation is parabola. Assume the volcano has no height.(1) When does the ash projectile reaches its maximum height?. (2) what is its maximum height. (3) When does the ash projectile reaches the ground?
