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?
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.
Power exerted at 11 s:
