So according to vertical motion, you add the accelaration to the initial velocity forever. Therefore, if the initial velocity is 6 and accelaration is -1, it should be:
6, 5, 4, 3, 2, 1, 0 (and that would make a total of 21) every second
but when I use the formula, d = -u^2/2a I get 18 instead? Why is this happening?
From 0 to 1 sec, the average velocity is (6 5)/2 = 5.5
The second second, the average is 4.5.
Then 3.5, 2.5, 1.5, .5
Add them up and you get 18.
Because acceleration doesn
