(99 points) while driving her new camaro at 20.0 m/s down a four-lane highway, jessica comes up behind a slow-moving dump truck and decides to pass in the left-hand lane. if jessica can accelerate at a rate of 5.0 m/s2, how long will it take for her to reach a speed of 30.0 m/s?

To go from 20.0 to 30.0 m/s, that is a velocity change of 10.0 m/s.

From the definition of acceleration,

a = (velocity change)/(time required)

In this case you know that a = 5.0 m/s^2, so

time = (10.0 m/s)/(5.0 m/s^2)

= 2.0 seconds

2 seconds

Explanation:

There is a velocity change of 10.0 m/s.

a = (velocity change)/(time required)  

From this a = 5.0 m/s^2, so

time = (10.0 m/s)/(5.0 m/s^2)

= 2.0 seconds

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
