what is the diameter of the football players' piston if the football players are held to a height 0.800 m above the cheerleader?

Sagot :

Diameter of the football players' piston if the football players are held to a height 0.800 m above the cheerleader is 53 cm

mass of the cheerleader is, m1=51.0kg

mass of each football player is, m2=110kg

diameter of the piston for cheerleader is, d1=18.0cm=0.18m

W1=m1g

W1=51.0kg×9.8m/s²

W1=500.31N

W2=4316.4N

P1=W1/(π/4d1²)

P1=500.31N/(π/4×(0.18m)²

P1=19660.94Pa

P2=5495.81/d2²Pa

P1=P2

19660.94Pa=5495.81/d2²Pa

d2=0.53 m

d2=53cm

so, the diameter of the football players piston is 53cm
