#2.5*4.8=12kg m s^-1#

Explanation:

Given:
Mass is a scalar quantity:

#m = 2.5"kg"#

Velocity is a vector:

#vecv = 4.8"m"/"s"" South"#

Momentum is a vector in the same direction as the velocity vector:

#vecp = m(vecv)#

Substitute in the given quantities:

#vecp = 2.5"kg"(4.84.8"m"/"s"" South")#

#vecp = 12"kg m"/"s"" South"#
