Third rocket Fourth rocket Initial upward velocity 200 200 Bursting altitude 450 700 The third and fourth rockets will both be launched with the given initial upward velocities in feet per second and are to burst at the specied altitude in feet. 7) 3) Write a quadratic equation in standard form to represent the altitude of the third rocket when it bursts. (Look at #5) h = -16t"2 + mm b) Write a quadratic equation in standard form to represent the altitude of the fourth rocket when it bursts. 8) a) Use the quadratic formula to nd the fuse time for the third rocket to the nearest tenth of a second. -16t"2+200t=450 b) Use the quadratic formula to find the fuse time for the fourth rocket to the nearest tenth of a second. i x
