Question
![**Projectile Motion Problem: A Football Throw**
**Problem Statement:**
A quarterback throws a football while standing at the very center of the field on the 50-yard line. The ball leaves his hand at a height of 6 feet and has an initial velocity \( \mathbf{v}_0 = 51\mathbf{i} + 37\mathbf{j} + 27\mathbf{k} \) ft/s.
Assume an acceleration of 32 ft/s² due to gravity and that the \( \mathbf{i} \) vector points down the field toward the endzone and the \( \mathbf{j} \) vector points to the sideline. The field is 150 feet in width and 300 feet in length. Determine the position function that gives the position of the ball \( t \) seconds after it is thrown. The ball is caught by a player 6 feet above the ground. Assume the player is standing vertically with both toes on the ground at the time of reception.
(Use symbolic notation and fractions where needed.)
\[ \mathbf{r}(t) = \]
**Question:**
Is the player in bounds or out of bounds when he receives the ball?
- [ ] The player is in bounds.
- [ ] The player is out of bounds.
**Discussion:**
When solving this problem, several key steps are involved:
1. **Set up the Equations of Motion**:
- In the x-direction (down the field), i-component.
- In the y-direction (side-line to side-line), j-component.
- In the z-direction (vertical), k-component considering gravitational acceleration.
2. **Equations of Motion**:
- The general form for each direction component:
\[
x(t) = x_0 + v_{0x}t + \frac{1}{2}a_xt^2
\]
\[
y(t) = y_0 + v_{0y}t + \frac{1}{2}a_yt^2
\]
\[
z(t) = z_0 + v_{0z}t + \frac{1}{2}a_zt^2
\]
