Comic-book superheroes are sometimes able to punch holes through steel walls. (a) If the ultimate shear strength of steel is taken to be 2.50 x 10 Pa, what force is required to punch through a steel plate 2.30 cm thick? Assume the superhero's fist has cross-sectional area of 9.00 x 10 cm? and is approximately circular. (b) Qualitatively, what would happen to the superhero on delivery of the punch? What physical law applies?
