Question

Fireworks are launched at the top of a 160 ft tower. It will launch at 92 ft per second. The people want the fireworks from each rocket to explode when the rocket is at the top of its trajectory. How long will it take for the rocket to reach the top? The rockets will be aimed at a field at an angle of 65 degrees above the horizontal. Equation: h = -16t^2 + v0t + h0 initial velocity v0 and initial height is h0 the team can find the horizontal distance to determine the rocket travels with this function: d (t) = 92t/tan65degrees
