An airport has runways only 198 m long. a small plane must reach a ground speed of 39 m/s before it can become airborne. what average acceleration must the plane's engines provide if it is to take off safely from its airport? answer in units of m/s 2 .

it would be kevlar ^^

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!
