a rocket is launched from the ground in vertical direction. but it\'s engine failed at the moment the rocket reached an altitude of 400ft and a speed of 600 ft/s. Determine the max height that the rocket can reach, determine the upward velocity 30 seconds after the engine has failed

Solution

Maximum height that the rocket can reach:

h=400 ft + 600^2/2g ft = 5990 ft

v=u-gt=600-32.2(30)
