Answer:

The object having a 7kg mass moving with 8m/s velocity has more momentum.

Explanation:

Linear momentum is defined as the product of the mass and velocity of the object.
#p=mv#.

Consider the object which has a mass 7kg and velocity 8m/s with linear momentum '#p_1#' and the other one with 4kg and 9m/s as '#p_2#'.

Now calculate the '#p_1#' and '#p_2#' with above equation and given numericals we get,
#p_1=m_1v_1=(7kg)(8m//s)=56kgm//s# and
#p_2=m_2v_2=(4kg)(9m//s)=36kgm//s#.
#:. p_1 >p_2#
