4. A rugby player of your choice and of mass 100 kg running at 6 ms' is tackled and brought to a halt in 0.1 s. The impact of the tackle is absorbed by one of his legs only, by the shearing of a particular bone (of cross-sectional area 3 104 m²). If the shear modulus of bone is 1010 N m² and the breaking strain is 103, calculate whether or not the bone will be broken. ANSWER: it will Hints: Find a relation between the acting force and the change in momentum.
