Question

16) As a person walks, their entire weight is momentarily placed on one heel of their shoes. a) Calculate the pressure in Pascals exerted on the floor by the heel if the person is walking in stiletto heels. Assume the heels have a circular cross section with a radius of 0.5 cm. and the person's mass is 55 kg. b) In the early days of commercial flight, people were not allowed to wear high- heeled shoes because aircraft floors were too thin to withstand such large pressures. Why would thin aircraft floors be useful for a plane (hint: don't overthink this)?

hi could someone assistant with this problem? Do I use F/A =mg/A? Do I need to find the area first. how do I solve. Could I get help with part a and b.
