3. Two cars are headed east on a straight road. In the reference frame of the road, Car A is traveling at +22 m/s, and car B is traveling at +30 m/s.
a. In the reference frame of car A what is the velocity of car B? what is the velocity of the road?
b. In the reference frame of car B what is the velocity of car A? what is the velocity of the road?

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

it would be kevlar ^^

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
