The same car, after crossing the finish line, has a velocity of 45m/s, after 25 seconds. What was the acceleration for this time period?

Explanation:

velocity(v)=45m/s

time(t)=25s

now,

=45

25

=1.8 m/s2

real, smaller and upside-down.   so the answer should be b.

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!
