How much power output does it take for you to get up the stairs?

Do You Have The Horsepower?

#1.  "find your weight in pounds and convert to kilograms" (1 pound = .45kg)

#2.  "calculate the force"    Force(N) = Mass(kg) X Acceleration(9.8m/s2)

#3. "measure the height of each stair (in cm) and multiply by the total number of stairs" (convert the cm into m)

#4. "calculate the work"  Work(J) = Force(N) X Distance(m)
#5. "measure the time (in seconds) it takes to climb the stairs"
#6.  "calculate the power" Power(J/S or Watts) = Work(J) / Time(S)
#7. "calculate the Horse Power"  1 HP = 746 Watts

$1 to any students who can beat my Horse Power
205 lbs
#1.  Mass(kg):   205 lbs X .45 kg/lbs = 92.3 kg
#2.  Force(N):   92.3 kg X 9.8 m/s= 905N
#3.  Distance(m):   17.5cm X 24 Stairs = 420cm or 4.2 m
#4.  Work(J):   905N X 4.2m = 3801J
#5. Time(s):   3.6 seconds
#6. Power(W):   3801J / 3.6s = 1056W
#7.  Horse Power:   1056W / 746W/HP = 1.42HP!
