Answer:

Step-by-step explanation:
1. The initial equation given to us is
. Rearranging the equation to isolate
, we have:

2. Using the equation we rearranged in part 1, we can substitute given values:

3. We see from our equation in part 1 (
) that when
, the denominator of our fraction will be equal to 0. Since we cannot divide by 0, the velocity remains undefined and cannot be determined.
