a. Estimate the force with which a karate master strikes a board, assuming the hand’s speed at the moment of impact is 10.0 m/s, decreasing to 1.00 m/s during a 0.002 s time internal of contact between te hand and the board. The mass of his and and arm is 1.00 kg . b Estimate the shear, assuming this force it exerted on a 1.00 cm thick pine board that is 10.0 m wide. c. If we maximum shear stress a pine board can support before breaking is 3.60 × 10^6 N/m^2, will the board break?
