A baseball has a mass of about 155 g. What is
the magnitude of the momentum of a baseball
thrown at a speed of 95 mph?(Note that you need to convert mass
to kilograms and miles per hour to meters per
second.)
Answer in units of kg · m/s

  1. mass = 155/1000 = 0.155 kg.

    V = 95mi/3600s * 1600m/mi = 42.2 m/s.

    Momentum=m*V = 0.155 * 42.2=6.54 kg.m/s
