We're going to learn more about why gravity accelerates all objects equally when we study Newton's Laws in the next section, where you'll discover how force is related to mass. Right now, here's another set of hints on solving physics problems...

Thank for catching that – I’ll get this fixed for you.
There is a typo in the Kinematic Equations on the top of the Student Worksheet. The t was omitted where the vt should have been. This error was carried into the solution for practice problem #14. The total time of 15.5 seconds was also used for the second leg of the pilot’s fall where 12 seconds should have been used. The time was also not squared and the deceleration of 2.5 m/s should be negative. When using the corrected equation, the proper time, negative acceleration and squaring the time; the distance of the second part of the fall is 228 meters. This makes the total fall of the pilot 288 meters. Using d=1/2 (Vi+Vf)t is an easier equation to use to determine the distance of the second part of the fall which produces the same result of 228 meters where Vi= 34 m/s, Vf= 4 m/s and t=12 s.
Yes, they are included for reference. You can recopy the questions or cover the answers to work the problems yourself.
So, are the answers supposed to be written in already on the practice problems set above?
