![### Solving Initial Value Problems for a Vector Function
#### Differential Equation
We are given a differential equation of the form:
\[ \frac{d^2 \mathbf{r}}{dt^2} = -20\mathbf{k} \]
#### Initial Conditions
The initial conditions provided are:
- \(\mathbf{r}(0) = 60\mathbf{k}\)
- \(\frac{d\mathbf{r}}{dt} \bigg|_{t=0} = 8\mathbf{i} + 8\mathbf{j}\)
These conditions specify the initial position and velocity of the vector function.
#### Problem Statement
Solve the initial value problem for \(\mathbf{r}\) as a vector function of \(t\). The goal is to determine \(\mathbf{r}(t)\) given the differential equation and initial conditions.
#### Approach
To solve this problem:
1. **Integration of the Differential Equation:** Integrate the given differential equation twice to find the expression for \(\mathbf{r}(t)\).
2. **Application of Initial Conditions:** Use the initial values to determine the constants of integration.
This process involves calculating the antiderivatives and applying known values to solve for any constants. Once solved, \(\mathbf{r}(t)\) will represent the position vector as a function of time.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffaca5e74-2c5e-414f-b942-28feaa05645e%2F8c68a88d-62e2-4f69-a0ff-1d36a31d5a1d%2Flgsjmbo_processed.jpeg&w=3840&q=75)
