An arrow in flight has an initial velocity of 65 meters per second and 10 seconds later it has a velocity of 35 meters per second. which is the acceleration of the arrow?

Explanation:

Given that,

Initial velocity of arrow, u = 65 m/s

Final velocity of arrow, v = 35 m/s

Time taken, t = 10 seconds

The acceleration of the arrow is given by the rate of change of velocity per unit time. It is given by :

The arrow in flight is decelerating. Hence, this is the required solution.

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..
