Question

### Educational Exercise: Physics of Human Towers

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) Question:
What is the normal force acting on the **67.0-kg** acrobat? (Enter the magnitude only.)

**Answer:** 2469.6 N ✔️

---

#### (b) Question:
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?

**Response:** 53686.96 Pa ❌

*Feedback:* Your response differs from the correct answer by more than 100%.

---

#### (c) Question:
Will the pressure be the same if a different acrobat is on the bottom?

**Answer:** Pressure will be the same since the total mass of acrobats remains the same.

---

This exercise demonstrates concepts of normal force and pressure in the context of a human tower, providing insight into static equilibrium and surface pressure distribution.
