$\textbf{Use equation of momentum}$

$p=mv$

$\text{momentum\ =\ mass x velocity}$

$\textbf{Substitute in the values}$

$5000 \times 75 = 375,000 \text{\ kg\ km/hr}$

$4200 \times 75 = 315,000 \text{\ kg\ km/hr}$

$\textbf{The\ small\ sports\ car\ will\ have\ the\ most\ momentum.}$

How does the momentum of a 75 kilogram stationary football player compare with that of a 70 kilogram player moving at a velocity

pashok25 [27]

Momentum of an object = (its mass) x (its speed) .

Since speed is a factor of momentum, an object that
isn't moving doesn't have any.

-- The moving player has momentum.

-- The stationary one doesn't.
