600 watts
The answer depends on the mass of the piano and the height of the floor.
Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts
Energy = Work = (force) x (distance) = (250) x (40) = 10,000 newton-meters = 10,000 joulesPower = energy/time = 10,000 joules/2 seconds = 5,000 watts = about 6.7 horsepower (rounded)

600 seconds is equal to 10 minutes. There are 60 seconds in a minute.

The answer depends on the mass of the piano and the height of the floor.
Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts
To lift a 950-N load 3 meters requires (950 x 3) = 2,850 joules of energy.The power is the rate at which the energy is delivered. It takes more powerto lift the load faster.The power used to lift this load is (2,850 joules) divided by (the number of seconds it takes),and the unit of the answer is watts.
Thrust: How much power that is being used to go forward. Lift on the other hand: is how much power that is used to gain altitude, like in a rocket ship or a plane.
Energy = Work = (force) x (distance) = (250) x (40) = 10,000 newton-meters = 10,000 joulesPower = energy/time = 10,000 joules/2 seconds = 5,000 watts = about 6.7 horsepower (rounded)
The power required to do 60 joules of work in 20 seconds is determined by the formula: Power = Work / Time. Therefore, Power = 60 joules / 20 seconds = 3 watts. So, 3 watts of power is necessary to do 60 joules of work in 20 seconds.

Power = (energy used) / (time to use that much energy) = 40/5 = 8 watts
Power is calculated by dividing the work done in Joules by the time taken in seconds. So, if x Joules of work are done in 10 seconds, the power used would be x/10 watts.
There are various prices of lift tickets at MT High. The prices for an Adult is $45 (Express Pass $39) and for children the lift ticket prices are $25. Anyone above the age of 70 or under the age of 6, the lift ticket prices are FREE.
