Problema Solution
After being launched, a rocket attains a speed of 122 m/s before the fuel in the motor is completely used. If you assume that the acceleration of the rocket is constant at 32.2 m/s^2, how much time does it take for the fuel to be completely consumed?
Answer provided by our tutors
let 't' represent the time in seconds before the fuel is completely consumed and assume that the rocket instantaneously achieves its constant acceleration of 32.2 m/s^2:
122 m/s = 32.2 m/s^2 * t
t = 122/32.2 = 3.788
it takes approximately 3.8 seconds for the fuel to be completely consumed
