Final answer:
The pressure exerted by a 60.0 kg student on the floor is calculated in two scenarios: flat-footed and wearing high-heeled shoes. The pressure is calculated by dividing the force exerted by the student by the surface area in contact with the floor.
Step-by-step explanation:
The subject of this question is Physics. The question asks for the pressure exerted by a 60.0 kg student on the floor in two different scenarios. For both scenarios, we can calculate the pressure by dividing the force exerted by the student by the surface area in contact with the floor.
a. When standing flat-footed in the laboratory, the surface area of the soles of the tennis shoes is approximately 180 cm². We calculate the pressure by dividing the weight of the student (force) by the surface area: Pressure = Force / Area = (60.0 kg * 9.8 m/s²) / (0.018 m²) = 32778.7 Pa.
b. As the student steps heel-first onto a dance floor wearing high-heeled shoes, the surface area of the heel is 1.0 cm². We calculate the pressure using the same formula: Pressure = Force / Area = (60.0 kg * 9.8 m/s²) / (0.0001 m²) = 5880000 Pa.
