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"
