Best ResponseYou've already chosen the best response.1to do this youy use one of the equations for constant acceleration the acceleration in this case is that due to gravity which = 32 ft s2 in this case we use 32 bacause it is acting against the motion of the rocket

Best ResponseYou've already chosen the best response.1use the formula v = u + at At maximum height the velocity v = 0 , a the acceleration = 32 , the initial velocity = 288 ft/sec and t is the required time solve for t
