A dragster going at 15 m/s increases its velocity to 25 m/s in in 2 seconds. What is its acceleration?

5m/s²

Explanation:

Given parameters:

Initial velocity  = 15m/s

Final velocity  = 25m/s

Time taken  = 2s

Unknown:

Acceleration = ?

Solution:

Acceleration is the rate of change of velocity with time taken. It is mathematically expressed as;

      Acceleration  =  

    Acceleration  =   = 5m/s²

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..

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
