Una bala se dispara a un angulo de 45° con respecto a la horizontal. la magnitud de la velocidad inicial de la bala es de 200 m/s. calcula: a) el tiempo que la bala permanece en el aire.
b) la posicion de la bala cuando alcanza la altura maxima​

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..
