Answer:

32500 kg m/s east, 42500 kg m/s west. Second car has larger momentum

Explanation:

The momentum of an object is given by

p = mv

where

m is the mass

v is the velocity

For the first car, m = 500 kg and v = 65 m/s east, so the momentum is

p_1 = (500)(65)=32500 kg m/s east

For the second car, m = 500 kg and v = 85 m/s west, so the momentum is

p_2 = (500)(85)=42500 kg m/s west

By comparing the two momentum, we see that the second car has larger momentum.

How do you tell a stars life expectancy based on an hr diagram?
e-lub [12.9K]
The X-axis of the H-R Diagram indicates the star's surface temperature in degrees Kelvin.  The Y-axis, on the other hand, indicates luminosity, or brightness.

Main sequence refers to a roughly diagonal, slightly S-curved line stretching between the upper-left and lower-right corners on which main sequence stars chart. They maintain a predictable relationship between luminosity and temperature: the brighter, the hotter. The upper-right quadrant of the H-R diagram is home to newly discovered red giants while the lower-left quadrant of the H-R Diagram belongs almost exclusively to white dwarfs.

A tennis ball is tossed up off a building with a velocity of 22m/s. It takes 6.4s to reach the ground. How high is the building
Amanda [17]
The height of the tennis ball,relative to the ground is H=h max+h-->h max-the maximum height that the tennis ball reaches relative to the roof of the building; h-the height of the building;h max =v0^2/2g=24,2m(g=10m/s^2).H=gt^2/2=>24,2+h=gt^2/2=>h=gt^2/2-24,2=180,6m
