To find the power exerted by the rocket, you can use the equation: Power = Force × Velocity. First, calculate the force using Newton's second law: Force = mass × acceleration. Then, use the formula for power and substitute the calculated force and the given velocity (since velocity is the rate of change of displacement and is constant during vertical acceleration).
Given: Mass (m) = 3500 tons Acceleration (a) = 8/5 m/s^2 Time (t) = 12 seconds
Calculations: Force = mass × acceleration Force = 3500 tons × (8/5 m/s^2)
Convert tons to kilograms: 1 ton = 1000 kg Mass = 3500 tons × 1000 kg/ton Mass = 3,500,000 kg
Force = 3,500,000 kg × (8/5 m/s^2)
Force = 5,600,000 N
Power = Force × Velocity Power = 5,600,000 N × (8/5 m/s)
Power = 8,960,000 watts
Therefore, the rocket will have to exert approximately 8,960,000 watts of power to maintain its acceleration after 12 seconds.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
