Question

What is the momentum of a 60kg running back heading towards the end zone at 9m/s?

Answer 1

P=mv so convert your mass and calculate .06*9=.54

Answer 2

momemtum equals the product of mass and velocity
\[\rho = mv\]
\[\rho = 60 \times 9 \]
the unit is \[kgms^{-1}\]

Answer 3

@c_c_mill the S.I unit of momentum is kgm/s or N.s
so you need not to convert the mass
