You are pushing a friend in a wagon. you push with a force of 40n. your friend and wagon together have a mass of 80kg. ignoring friction, what is the acceleration of your friend on the sled?

a= 0.5 m/s^2

Explanation:

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..

the entire statement is true and correct.  

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