WebJun 8, 2016 · The rocket will be in the air for 10 seconds. We have to find out the positive values of x for which h(x)>=0. We can do it algebraicly: -16t^2+160t>=0 -16t*(t-10)>=0 t_1=0, t_2=10 Since the coefficient next to x^2 is nagative (-16), the solution of this inequality is t in <0;10>, so the rocket's flight will last 10 seconds. We can also solve this task using graph … WebFind step-by-step Physics solutions and your answer to the following textbook question: A fireworks rocket is fired vertically upward. At its maximum height of 80.0 m, it explodes and breaks into two pieces: one with mass 1.40 kg and the other with mass 0.28 kg. In the explosion, 860 J of chemical energy is converted to kinetic energy of the two fragments.
