Final answer:
The basketball has more momentum than the bowling ball because its momentum is 55.8 kg·m/s compared to the bowling ball's 38.5 kg·m/s.
Step-by-step explanation:
The momentum of an object can be calculated by multiplying its mass by its velocity. In this case, the momentum of the bowling ball can be calculated as (5.5 kg) * (7.0 m/s) = 38.5 kg·m/s. Similarly, the momentum of the basketball can be calculated as (6.2 x 10^0 kg) * (9.0 m/s) = 55.8 kg·m/s.
Therefore, the basketball has more momentum than the bowling ball.
