3. Given: A 20 g-bullet with 0.5 cm diameter and an acceleration, a= 1.5 x106 ft/s² is fired from a rifle and hits a target made from wood. The piece of wood is 0.3 cm thick and has a maximum shearing strength of 87 ksi. The friction effects between the bullet and wind; and the effects of gravity are neglected. Find: shear stress made by the bullet into the wood.
