Object having mass #8 kg# has more momentum.

Explanation:

Momentum is given by product of mass and velocity.
So, #p=mxxv#

Momentum of object having mass #8 kg# # = 8xx4#

Momentum of object having mass #8 kg# # =32kgms^-1#

Momentum of object having mass #7 kg# # = 7xx5#

Momentum of object having mass #8 kg# # =35kgms^-1#

Hence, Object having mass #8 kg# has more momentum.
