question 61

Multiple Choice

What pressure (in Pa) will be exerted on the bottom of a 63.5 kg hiker's foot when she stands on a rusty nail? Assume the diameter of the tip of the nail is 1.00 mm. The acceleration due to gravity is 9.81 m/s². Recall that the area of a circle is: A = $\pi$ r² and that 1 Pa = 1 kg m^-1 s^-2.
