So in this problem, we're told that a box is topped upward from a cliff that is 6 meters high at a speed of 10 meters per second.
00:06
We want to know the height after one second.
00:08
So we're given this formula to represent the height for any object in freefall.
00:12
So what we need to do is we need to substitute in the information that we know.
00:16
Well, we know that we're trying to figure out after one second, which means we're trying to find h of 1.
00:22
So we're going to be plugging in 1 for t.
00:23
All right, so let's go through the equation.
00:25
So first, we have negative 1ā2 times g, which they tell us is 9 .8 meters.
00:30
Second squared, and then we have t, which is 1, so 1 squared.
00:34
Plus, well, next, that's v0 represents the initial velocity, which we were told the initial velocity was 10 meters per second.
00:41
So that would be our v .0 value...
