A50-kg object moving at 12 m/s has a momentum of 600 kg ´ g m/s. what is the mass of an object, moving at 4 m/s that has the same momentum?

150 kg

Step-by-step explanation:

Momentum is calculated using the following equation:

p = m*v

where p is the momentum kgm/s

          m is the mass in kg

           v is the velocity m/s

So for a body whose momentum is 600 kgm/s and the v is 4 m/s, then

600 kgm/s = m* 4 m/s

               m = 150 kg
