Question

At what speed do a bicycle and its rider, with a combined mass of 100 kg , have the same momentum as a 1600 kg car traveling at 5.2 m/s ?

Answer 1

`Given:\\m_b=100kg\\m_c=1600kg\\v_c=5.2 (m)/(s) \\p_b=p_c\\\\Find:\\v_b=?\\\\Solution:\\\\p_b=p_c\\\\p=mv\\\\m_bv_b=m_cv_c\Rightarrow v_b= (m_cv_c)/(m_b) \\\\v_b= (1600kg\cdot5.2 (m)/(s) )/(100kg) =83.2 (m)/(s)`
