Question
A model rocket rises vertically from rest with a constant acceleration of 3.23 m/s2 until it runs out of fuel at an altitude of 948 m. Neglect air resistance and take upwards as the positive direction for position and velocity.
(a) What maximum altitude does the rocket reach? (answer: 1260 m)
(b) How much time does the rocket take to reach its maximum altitude? (answer: 32.3 s)
(c) What is the velocity of the rocket at the moment it hits the ground? (answer: - 157 m/s)
(d) What is the total flight time of the rocket from the moment it is launched until the moment it hits the ground? (answer: 48.3 s)
