Momentum is the product of mass and velocity.

For the $1$ st object momentum is $7×3=21 Kg.ms^-1$

And for the $2$ nd object momentum is $4×7=28 Kg.ms^-1$

So,clearly the $2$ nd object has higher momentum.

Which has more momentum, a 7kg7kg object moving at 3m/s3m/s or a 4kg4kg object moving at 7m/s7m/s?
