Question

Two rugby players run towards each other and have an inelastic collision. Given the mass 70 kg and 60 kg respectively, and velocity 3 ms-1 and 4 ms-1. Calculate the final velocity and its direction of the respective players. Discuss how a rugby player’s bone develops if continuously performing the weight bearing exercise using Wolff’s Law and bone remodeling theory

Answer 1

$m_1v_1+m_2v_2=(m_1+m_2)u,$

$u=\frac{m_1v_1+m_2v_2}{m_1+m_2},$

$u=-0.23~\frac ms.$
