Honors Physics 2B
People former
Purpose: The objective of this lab is to puzzle out the amount of power generated by humans.
Materials:
Procedure:
1. learn the plenty of soulfulness A in kilograms.
2. Measure the vertical vertex of the stairs from the basement to the twinkling floor in meters. Record your result
3. Climb the stairs.
4. Record Person As bonny time to the nearest .1s
5. Repeat 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 found that this was 3.76 meters. To find the peck of each person, we compute their weight 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 Power= (Work/Time)
exercising 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 PEg=(85.0939)(9.81)(3.76) 689.7= 843.77 v
Horsepower= .925hp PEg=3138.
74J .82 m/s = velocity
Person B (140 lbs x .454 = 63.56 kg)
Weight=mass(gravity) Work=(Fcos?)s Power= (Work/Time)
Weight=63.56kg(9.81) Work=(623.5cos0)3.76 Power= (2344.4/14.53)
Weight=623.5 N Work= 2344.4 J Power= 161.3 W
Horsepower= Watts/746 PEg=mgh Power= Force(velocity)
Horsepower= 161.3/746 PEg=(63.56)(9.81)(3.76)...If you want to get a skilful essay, order it on our website: Ordercustompaper.com
