Part a, we can use the kinematic equation.
00:04
V final equals v initial plus the acceleration times t.
00:07
We know that the initial velocity would be zero, and so the final velocity in this case would be equaling the acceleration.
00:14
We know it to be 4 .50 meters per second squared, multiplied by t 2 .40 seconds.
00:22
This is equaling 10 .8 meters per second.
00:26
This would be your answer for part a.
00:29
Now for part b, we're going to determine the position.
00:33
We know that delta x is equaling vx initial times t plus one half times the acceleration in the x direction times t squared.
00:43
We know that this term is going to be zero because the initial x velocity is equaling zero.
00:48
And so the change in displacement, or rather the displacement, the change in distance between your end position and your origin would be equaling to one half times.
00:59
The acceleration in the x direction times t squared...
