DETAILS 777777.78 Pa MY NOTES A 70.00kg ballroom dancer wearing high heels accidentally steps on her partner's foot. If her entire weight was momentarily supported by the heel of her shoe, which has a surface area of 0.90 cm², what amount of pressure does this apply to her partner's foot? 762.22 Pa 76222.22 Pa 7622222.22 Pa ASK YOUR TEACHER Suppose she instead stepped on her partner's foot with her forefoot instead of her heel (i.e., larger surface area). Would the pressure on her partner's foot be greater, less than, or equal to if she stepped on her partner with her heel? The pressure from the forefoot would be greater than the pressure from her heel. The pressure from the forefoot would be equal to the pressure from her heel. The pressure from the forefoot would be less than the pressure from her heel.
