Question
Four acrobats of mass 67.0 kg, 68.0 kg, 62.0 kg, and 55.0 kg form a human tower, with each acrobat standing on the shoulders
of another acrobat. The 67.0-kg acrobat is at the bottom of the tower.
(a) What is the normal force acting on the 67.0-kg acrobat? (Enter the magnitude only.)
2469.6
✔N
(b) If the area of each of the 67.0-kg acrobat's shoes is 500 cm2, what average pressure (not including atmospheric
pressure) does the column of acrobats exert on the floor?
53686.96 X
Your response differs from the correct answer by more than 100%. Pa
(c) Will the pressure be the same if a different acrobat is on the bottom?
Pressure will be the same since the total mass of acrobats remains
the same
