Upon landing, a rightward-moving airplane accelerates from 65 m/s to 10 m/s in 4.9 s. Determine the average acceleration of the airplane in m/s/s. Enter a numerical answer (no units) accurate ... .
(Note: Numbers are randomly generated and may differ from those shown here.)
The numerator in the acceleration equation (see Formula Fix section) is the change in velocity. A changein any value is found by subtracting the initial value from the final value. In this question, such a change will be negative. But don't be fooled! The question asks you to enter the magnitude of the acceleration; ignore + and - signs which are indicators of a direction.
The Minds On Physics program calculates answers accurate to several decimal places. Your answer does not need to be that precise. The program will allow you to have a 1% deviation from the right answer without being wrong. This means you should enter your answer to at least the second decimal place.
