Answer:

The momentum of the second object is larger.

Explanation:

The formula for momentum is

#p = m*v#

Therefore you simply multiply mass times velocity for each object.

#5 " kg moving at " 3 m/s#:
#p_1 = 5 " kg " * 3 m/s = 15 ("kg*m)/s#

#9 " kg moving at " 2 m/s#:
#p_2 = 9 " kg " * 2 m/s = 18 ("kg*m)/s#

I hope this helps,
