# 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:**
