If a rocket with a mass of 4000 tons vertically accelerates at a rate of # 6/5 m/s^2#, how much power will the rocket have to exert to maintain its acceleration at 11 seconds?

Explanation:
First we will calculate the thrust force of the rocket, then we will find the velocity of the rocket at 11 seconds and lastly calculate the power at 11 s required to maintain its acceleration at that velocity.
Thrust force (using simplified version of Newton’s second law):
Mass: m = 4000 tons
Velocity of the rocket at 11 s:
Use equation of constant acceleration, assuming it starts at rest.
Use
Power exerted at 11 s:
