Final answer:
The momentum of a bowling ball can be calculated by multiplying its mass and velocity. In this case, the momentum is 50 kg.m/s.
Step-by-step explanation:
The subject of this question is Physics, specifically the concept of momentum. Momentum is the product of an object's mass and its velocity. In this case, the bowling ball has a mass of 5 kg and a velocity of 10 m/s. To calculate the momentum, we multiply the mass and velocity together: 5 kg * 10 m/s = 50 kg.m/s.
