1. The problem statement, all variables and given/known data A model rocket blasts off from the ground, rising straight upward with a constant acceleration that has a magnitude of 79.0 m/s2 for 1.90 seconds, at which point its fuel abruptly runs out. Air resistance has no effect on its flight. What maximum altitude (above the ground) will the rocket reach? 2. S=.5at2^2 3. The attempt at a solution S= .5(79)(1.90)2 =142.595 S=142.595^2/(2*9.8) =1037.42 142.595+1037.42=1080m.... only 3 sig figs It says its wrong?
