A person whose mass is 72 kg has a momentum of 700 kg/m/s (E). What velocity must this person be travelling at? (2 sig figs)

From the information given, the mass of the moving body, which in this case is a person, is 72 kg and the momentum 700 kg m/s. we use the formula p = m * v. Where p is momentum, m is the mass and v is the velocity. We need v so we rewrite the equation thus: v = p/m In our case p = 700 and m = 72 v = p/m → v = 700 / 72 → v = 9.72 Therefore the person is travelling at 9.72 m/s
