Energy = Work = (force) x (distance) = (250) x (40) = 10,000 newton-meters = 10,000 joules
Power = energy/time = 10,000 joules/2 seconds = 5,000 watts = about 6.7 horsepower (rounded)

How much power does it take to lift 30 N 10 m high in 5 seconds?
600 watts
What does 2 to the second power mean?
2 to the second power means 2x2 (also written as 2^2) which equals 4. The big number is what you’re actually multiplying and the small number at the top (exponent/power) is how many times you’re multiplying it.
What is zero to the fourth power?
Zero to any non-zero real number power is equal to zero. Unless a function evaluates to 'zero to the infinity power' then you must take limits to determine what the limit evaluates to. Zero to the zero power is undefined, but you can take a limit of the underlying function to determine if the limit exists.
If there is a fourth dimension then why is there no name for the fourth power?
If a number raised to the second power is squared and raised to the third power is cubed, I'm going to take a guess and say that a number raised to the fourth power is tesseracted.

How much lift does it take for an airplane to get off the ground?
In order to lift off the ground, the lift force (the upward force generated by the wings) has to be at least as great as the weight of the aircraft. Lift and weight are opposing forces and are equal in straight and level flight.
