Question

You already know a principle of science that "An object falls freely with constant acceleration of it falls at a height h"
If a substance falls freely from a tower, it's velocity is increased by 9.8m/s then find velocity of a object after 10 sec. (Solve it in form of AP) ​

Answer 1

first term a=9.8

common diff d= 9.8

tenth term =a+9d=9.8 +9×9.8

=98
