People Power Physics Lab

Nicholas Ferraro February 27, 2010 Honors Physics 2B People former Purpose: The objective of this research lab is to puzzle out the amount of power generated by humans. Materials: functioning: 1. learn the plenty of soulfulness A in kilograms. 2. measuring stick the perpendicular vertex of the stairs from the basement to the twinkling shock in meters. Record your result 3. Climb the stairs. 4. Record individual As bonny time to the nearest .1s 5. copy steps 1, 3, and 4 for Person B Results/Observations: We measured the vertical height of the stairs from the basement to the second floor and establish that this was 3.76 meters. To find the peck of each person, we compute their cant over in pounds by .454 to get the value in kilograms. To find the weight of person A and B, we multiplied their mass in kilograms by 9.81. Person A (187.6 lbs x .454 = 85.0939 kg) burthen= mass(gravity) doing=(Fcos ?)s queen= ( school/Time) use weight= 85.0939kg( 9.81) Work= (843.77cos0) 3.76 Power= (3172.6J/4.6s) Weight= 843.77 N Work= 3172.6 J Power= 689.7 W Horsepower= Watts/746 wooden leg=mgh Power= Force(velocity) Horsepower= 689.7/746 leg=(85.0939)(9.81)(3.76) 689.7= 843.77 v Horsepower= .925hp PEg=3138.
