What would have greater power an elevator or stairs?
Stairs have no power at all. They simply make it possible for you to direct your own power in a direction that will accomplish a certain result when you use them. Elevators use electrical power and deliver it in a mechanical form for your use.
Is there some limit to the height of the flight of stairs used and the horsepower developed?
There's no limit to the height of the stairs, but because power is the rate of doing work, different people would run up several flights of stairs at different rates, since each person has a "limit" on the amount of power she/she can produce.
What is the average power supplied by a 60.0 kg secretary running up a flight of stairs rising vertically 4.0m in 4.2 seconds?
NO ANSWER?!....This is unacceptable in this organization. -.-
How much power is used by a 40 kg athlete climbing a 10 m high ladder in 10 s?
Power = Work / Time Work = Force x Distance Therefore: Work = 40 x 9.81 x 10 Work = 3924 Joules Power = 3924 / 10 Power = 392.4 Watts.

What happens to the amount of power expended when you are climbing stairs and then climb faster?
I believe that the amount of power/energy you exert on yourself climbing up the stairs is wasted, and the faster you go, the faster the power is used up. It takes a lot of energy to go up one flight of stairs than it does going down five or so, depending on the body type of the person and maybe even the amount of gravity in that specific area.

Will you have the same power if you run up the same stairs?
It takes more power to run up the same stairs faster.
How could you increase power if you walked up the stairs in ten seconds?
You can increase power by walking up the stairs in LESS time.

How does your power in climbing a flight of stairs compare with the power of a 100 W light bulb?
One joule is the amount of energy required to apply a force of one newton through a distance of one meter (one newton-meter), or it is the amount of energy required to produce one watt of power for one second (one watt-second).If we assume that you have a mass of 200 pounds or 91 kilograms, then it requires a force of 891 newtons (91 * 9.82) to support you. This force will be the same whether you are standing still or climbing, even though it will momentarily change when you accelerate, so we can use 891 newtons.If we then assume that a flight of stairs is about 3 meters, we can calculate the power to climb up at 891 * 3 = 2672 joules per flight.Lets look at the light bulb. That one is easy. 100 watts is 100 joules per second.Now the question is, how fast can you climb? Let assume 10 seconds per flight of stairs. That translates to 267 joules per second, so you use nearly three times the energy of a 100 watt light bulb to climb stairs. (Two times, if you climb a little bit slower.)
Dan climbs a flight of stairs in 0.025 s. If he weighs 550 N and the stairs is 10 m from the ground, how much power in watts will he developGIVEN:UNKNOWNEQUATION: SOLUTION?
a lot
Need a hypothesis for how does your power in climbing a flight of stairs compare with the power of a 100 W light bulb?
A hypothesis could be that your power is the same. Or it could be that your power is a million times greater or only one millionth. You decide!A hypothesis could be that your power is the same.
