Okay, so we're giving it this problem.
00:04
We have a function for acceleration, so a of t is equal to negative 32.
00:10
We know that at times zero, the velocity is 50, and this distance is zero.
00:16
So what we're going to do first, we're going to figure out what the velocity is.
00:20
The function of the velocity, we can figure that out by finding the antiderivative of the...
00:31
We're going to find the anti -derivative of the acceleration, which just becomes...
00:35
Negative 32 t plus c.
00:39
Remember we do negative 32 t because we are adding one to the exponent of the variable and then we're dividing by that number because this is equal to one we divide by one.
00:53
To figure out what c is equal to, we're going to use v of zero is equal to 50.
01:01
This is equal to zero plus c.
01:03
This cancels.
01:04
C must be equal to 50.
01:06
So we get negative 32t plus 50...
