The y-component of a projectile’s velocity is 12.1 m/s. when the projectile once again passes by the height from which it was launched, what is the y-component of its velocity? impossible to calculate without knowing the x-component 0 m/s 12.1 m/s -12.1 m/s

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..
