Power = (energy) / (time) = (35 x 5) / 19 = 175 newton-meters / 19 seconds = 9.2105 watts (rounded)
6.7 times 10 to the -3 power
2.6 hours = 2.6*60 minutes = 156 minutes = 156*60 seconds = 9360 seconds.
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
a lot
NO ANSWER?!....This is unacceptable in this organization. -.-
25 watts NOOOOOOOOOOOO! you are sooo wrong,. i hate to correct you but it bloody 250 okay so when you give an answer MAKE SURE ITS FRIKEN WRITE NEXT TIME BLACKMAN!
To raise 100 KG by 14 meters the work done is 100 x 9.81 x 14 = 13734 Joules. (9.81m/sec2 is the acceleration of a body in free fall, commonly called 'g') To do this work in 10 seconds means a power of 1373.4 Joules/second = 1373.4 watts
You can increase power by walking up the stairs in LESS time.
400
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.
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.
It takes more power to run up the same stairs faster.
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.)
Escalator
Calculate the energy required to raise the person (weight x height). Then divide that energy by the time, to get power.
