Which has more momentum, a 0.046-kilogram golf ball with a speed of 60.0 meters per second, or a 7.0-kilogram bowling ball with a speed of 6.0 meters per second?

Bowling ball

Explanation:

Momentum, p is calculated by multiplying the mass and velocity of an object hence expressed as p=mv where m and v represent mass and velocity respectively.

Momentum of golf ball

For the golf ball, the momentum will be given by substituting 0.046 kg for m and 60 m/s for v hence moment is equivalent to 0.046 kg*60 m/s=2.76 kg.m/s

Momentum for bowling ball

The momentum of bowling ball is also calculated by substituting the mass as 7kg and velocity as 6 m/s hence p=7*6=42 kg.m/s

Evidently, 42 is greater than 2.76 hence momentum of bowling ball is the greatest of the two
