a rocket is being fired from the ground at angle of 530. while the rocket fuel lasts the rocket accelerates uniformly for 4 sec and reaches a speed of 100 m/s starting from rest. ignore air resistance a) determine the maximum altitude that the rocket will attain before it falls back to the ground. b) determine the total time the rocket is above the ground. c) sketch graphs of y vs. x for this motion. d) sketch graphs of the position, velocity and acceleration vs. time for the horizontal motion and also for the vertical motion. how would the above graphs change if, instead of being constant, the initial acceleration of the rocket had increased uniformly from zero during the 4-sec booster phase? e)
