Question

A ballet dancer who has a weight of 480 N stands on her toes during a performance with 25 cm2in contact with the floor. What is the pressure exerted by the dancer on the floor?

Answer 1

Pressure = F/A

Force = Weight = 480N

Area = 25cm²

However, Area in m² 1cm² = 0.0001m²

Thus, 25cm² = 25 x 0.0001

= 0.0025m²

Therefore, Pressure = 480N/0.0025m²

= 192,000 N/m²

or 192,000 Pa
