Problem 1, 15 points Arocket i lunched vertically from point Po(0), with the rocket motor providing thrust equivalent to an acceleration of 19.8 m/s2. After 3 seconds, the rocket reaches point P, and the rocket motor shuts down. For I second (up to a total flight time of 4 seconds), the rocket flies without thrust, while it rotates by 45o. Then, at point P2 the rocket motor is restarted, again providing thrust equivalent to an acceleration of 19.8 m/s? in...
