Problem

Two packages are launched from the same point. Package P

_1

has mass

2\,\text{kg}

and velocity components

(6,\,2,\,-3)\,\text{m\,s}^{-1}

along the

x

y

, and

z

axes. Package P

_2

has mass

3\,\text{kg}

and velocity components

(4,\,-1,\,2)\,\text{m\,s}^{-1}

. Which statement about the magnitudes of their linear momenta is correct? a) Momentum of P

_2

is greater than that of P

_1

b) Both packages have equal momenta,

\approx 14\,\text{kg m s}^{-1}

c) Momentum of P

_1

is greater than that of P

_2

d) Both packages have momentum magnitudes less than

10\,\text{kg m s}^{-1}
