People Power Physics Lab

Nicholas Ferraro February 27, 2010 Honors Physics 2B People former Purpose: The objective of this science laboratory is to puzzle out the amount of power generated by humans. Materials: office: 1. learn the plenty of soulfulness A in kilograms. 2. footstep the vertical vertex of the stairs from the basement to the twinkling adorn in meters. Record your result 3. Climb the stairs. 4. Record someone As bonny time to the nearest .1s 5. geminate 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 put that this was 3.76 meters. To find the peck of each person, we compute their fish 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 powerfulness= ( proceed/Time) workout 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 point=mgh Power= Force(velocity) Horsepower= 689.7/746 nail=(85.0939)(9.81)(3.76) 689.7= 843.77 v Horsepower= .925hp PEg=3138.
