To solve this question there are two steps involved. One, find the velocity function and two, substitute the specific time into the velocity function.

To get the equation for velocity, we take the derivative of the position equation.

Recall the rules of differentiation to solve this problem, specifically the power rule which states,

and the constant rule which states that the derivative of a constant is always zero.

Applying the power rule to each term of the position function will result in obtaining the velocity function.

To solve this, we'll need to first differentiate the position function to get the velocity function, and then plug our specific time into that velocity funtion to get the velocity at that moment. Differentiating the position equation term-by-term, using the power rule, which states that

and the constant rule, which states that the derivative of a constant is 0, we get

To solve this problem, you must first find the velocity function. To do that you, you need to find the derivative of the position function. Remember, when taking the derivative, multiply the exponent by the coefficient in front of the x and then subtract 1 from the exponent. Therefore, the velocity function is: . Then, set that expression equal to 0 to get your x:
