What is the work done when a person with a mass of 0.15 kg travels up a flight of stairs with height of 1.25 m?

0.15 kg? Even newborn premature baby has more mass than that. - Anyway, to calculate the work done, you use the same formula as for gravitational potential energy: mgh (mass x gravity x height), where "gravity", in SI units, is approximately 9.8.

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.
If you exert a force of 700 N to walk 6 m up a flight of stairs in 6 s how much power do you use?
Calculate the energy required to raise the person (weight x height). Then divide that energy by the time, to get power.
How many joules in a cornflake?
There are 1000J in a single flake!! This is also the amount of joules needed to climb an average flight of stairs!!
What is the average power supplied by a 60.0 kg person running up a flight of stairs a vertical distance of 4.0 m in 4.2 s?
Calculate how much his potential energy increases in one second. Use the formula PE = mgh (mass x gravity x height), mass in kg, gravity = 9.8 (meters per second squared), convert height to meters. Result will be in Joules. The standard unit of power, Watts, means Joules / second.
What is the horsepower of a 120 lb person walking up stairs?
