A)50 m/s.
B)500 m/s.
C)3000 m/s.
D)3600 m/s.
E)none of the above

Quizplus · Accepted Answer

The speed of the rocket can be calculated using the formula: final speed = initial speed + (acceleration × time). Since the rocket starts from rest, the initial speed is 0. The acceleration is 50 m/s² and the time is 1 minute (60 seconds). Therefore, the final speed is 0 + (50 m/s² × 60 s) = 3000 m/s.
