Because we're told we can assume that the acceleration is constant in this problem, we're going to want to use the kinnematic equations to solve.
00:13
And we're trying to figure out the velocity, the final velocity.
00:21
Unfortunately, even though we're told the acceleration is constant, we're not told what it is.
00:27
And in order to actually solve any of the kinnematic equations, we need to know what that acceleration is.
00:35
So ultimately, i want to find the velocity by using the kinematic equation.
00:40
That final velocity is equal to initial velocity plus acceleration times time.
00:47
We know the time.
00:48
We know the initial velocity is zero.
00:50
So it'll be pretty easy to solve, but we need acceleration first.
00:55
The only other thing we don't have is the final velocity.
00:59
So looking through the kinematic equations, i note that the second kinematic equation only involves things that we currently know and acceleration...
