A rocket is launched from the origin with an acceleration of 20.0 m/s² at an angle of 30.0 degrees above the horizontal. The launch acceleration lasts for 2.00 seconds at which time the fuel is exhausted. The rocket then falls with an acceleration of 9.80 m/s² downward. What is the maximum velocity reached in the upward direction? A) 20.0 m/s B) 25.0 m/s C) 30.0 m/s D) 35.0 m/s E) 40.0 m/s

Question

Quizplus · Accepted Answer

The correct answer is A. The maximum velocity reached in the upward direction is 20.0 m/s. This is because the rocket's initial vertical velocity is 20.0 m/s, and its acceleration in the upward direction is 0 m/s^2. Therefore, its vertical velocity remains constant at 20.0 m/s until the fuel is exhausted.
