Answer:
A bowling ball
Step-by-step explanation:
Momentum is the product of mass and velocity. It is a vector quantity that is has both direction and magnitude. It is measured in kg-m/s

where, m is the mass and v is the velocity.
The golf ball and bowling ball are moving with the same velocity but they have different mass. Bowling ball is heavier than a golf ball. Thus, the momentum of bowling ball would be more than that of the golf ball.
