Answer
The momentum of the automobile is $~~35,000~kg~m/s~~$ to the south
Work Step by Step
We can find the automobile's mass:
$mg = 9800~N$
$m = \frac{9800~N}{9.80~m/s^2}$
$m = 1000~kg$
We can find the momentum of the automobile:
$p = mv = (1000~kg)(35~m/s) = 35,000~kg~m/s$ (to the south)
The momentum of the automobile is $~~35,000~kg~m/s~~$ to the south.
