# If a rocket with a mass of #900 kg# vertically accelerates at a rate of # 2 m/s^2#, how much power will the rocket have to exert to maintain its acceleration at 4 seconds?

To find the power exerted by the rocket, you can use the formula ( P = F \cdot v ), where ( P ) is power, ( F ) is force, and ( v ) is velocity. The force exerted by the rocket can be calculated using Newton's second law: ( F = m \cdot a ), where ( m ) is mass and ( a ) is acceleration. Then, you need to calculate the velocity of the rocket at 4 seconds using the formula ( v = u + at ), where ( u ) is initial velocity (assumed to be 0 m/s because it starts from rest), ( a ) is acceleration, and ( t ) is time. Finally, plug the values into the power formula to find the answer.

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.

- An object with a mass of #7 kg# is hanging from an axle with a radius of #8 cm#. If the wheel attached to the axle has a radius of #56 cm#, how much work would it take to turn the wheel a length equal to the circumference of the axle?
- How much work would it take to push a # 2 kg # weight up a # 3 m # plane that is at an incline of # pi / 3 #?
- How much work would it take to push a # 5 kg # weight up a # 2 m # plane that is at an incline of # pi / 6 #?
- A balanced lever has two weights on it, the first with mass #72 kg # and the second with mass #9 kg#. If the first weight is # 2 m# from the fulcrum, how far is the second weight from the fulcrum?
- How much work would it take to push a # 1 kg # weight up a # 2 m # plane that is at an incline of # pi / 6 #?
