Question #144542
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?
Expert's answer
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
