Question

A model rocket blasts off with a constant acceleration of 12.3 m/s2 until its fuel runs out 10.2 s later. It then enters free fall for the remainder of its flight.
a) Calculate the maximum height above the ground reached by the model rocket.
b) Calculate the total time the rocket is in the air. (Careful: There are two different
accelerations on the way up, but only one on the way down. This creates three parts to the
motion.)

Answer 1

The answer is option A

This is the anwer because We need to calculate the maximum height reached into the sky within a certain amount of distance.
