To find the position function, you must integrate the velocity function. To integrate, add 1 to the exponent and then put that result on the denominator. . Then, plug in your initial values to find your C: . Then, . Therefore, your answer is: .

We'll need to find the acceleration, and then work backwards to find the position. We can rewrite Newton's Second Law as , which in this case gives us an acceleration of

Initial and final time are given as 

Acceleration is the rate of change in velocity, which is the rate of change in position, so to find the equation for position, we'll ned to integrate and use initial conditions twice. 

To integrate, we use the following rule:

Remember, when integrating we have to add the constant, C, to indicate that there's multiple functions that could be our answer.

Integrating then gives us:

The first step in solving this problem is integrating the velocity function to get your position function. When integrating, remember to raise the exponent by 1 and then also put that result on the denominator: . Now, to figure out what C is, plug in your initial conditions given: . Plug in 4 for C to get your answer: .

First, you need to find the derivative of the function. When taling the derivative, multiply the exponent by the coefficient in front of the x term and then decrease the exponent by 1. Therefore: . Now, plug in 1 for x to get your answer: 11.

To find the position function from the velocity function, you must integrate the velocity. When integrating, raise the exponent by 1 and then put that result on the denominator as well: . Then, plug in your initial conditions to find C: . Therefore, the position function is:
