You throw a ball straight up at 45 m/s. how many elapse before it is traveling at 5 m/s?

4.08 s

Explanation:

We can solve this problem with the following equation:

Where:

is the final velocity of the ball

is the initial velocity of the ball

is the acceleration due gravity

is the elapsed time

Isolating :

This is the elapsed time

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..
