Four acrobats of mass 72.0 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 72.0-kg acrobat is at the bottom of the tower. (a) What is the normal force acting on the 72.0-kg acrobat? (Enter the magnitude only.) N (b) If the area of each of the 72.0-kg acrobat's shoes is 390 cm², what average pressure (not including atmospheric pressure) does the column of acrobats exert on the floor? Pa (c) Will the pressure be the same if a different acrobat is on the bottom?
