How long does it take for the speed of light and sound to travel around the world

-- Light travels straight, not around in a circle. But if it did, it would cover
a distance equal to the length of the equator in about <em>0.13 second</em>.

-- At the speed of sound (in air at standard temperature and pressure),
it would take about <em>32.6 hours </em>to cover the same distance.

A 10 kg cart is rolling across a parking lot with a velocity of .5 m/s. What is its momentum?

-Dominant- [34]

Hello!

$\large\boxed{p = 5 \text{ } kgm/s}$

Use the equation for momentum:

$p = mv$

Plug in the given mass and velocity into the equation:

$p = 10 * 0.5$

$p = 5 kgm/ s$
