"A model rocket is launched straight upward from the ground with an initial speed of 53.3 m/s. It rises with a constant upward acceleration of 1.86 m/s^2 until its engines stop at an altitude of 161 m. What is the maximum height reached by the rocket?"© BrainMass Inc. brainmass.com March 4, 2021, 5:44 pm ad1c9bdddf
Solution. We can think about this problem in the following way. First, the rocket can go upward with a constant acceleration a=1.86m/s^2 until its engines stop at an altitude of 161m. We can compute the time T it takes. Then, its engines stop and the rocket will decrease its speed to zero because of the gravity. When its speed ...
The solution clearly explains the problem and provides formulas and calculations to arrive at the answer.
