Expert Answer

Step 1

Explanation:-Since, acceleration due to gravity near the surface of the earth and upto some height (within few kilometers) are constant. its value is g = 9.8 m/s^2 in downward direction. Although the value of accleration due to gravity decreases as the height of object increases, but this change in acceleration is very very small upto some kilomet...
