Final answer:
The second-order boundary value problem that models the problem is y''(t) = -g.
Step-by-step explanation:
When a projectile is thrown from the top of a building, it follows a parabolic path. In this case, the boundary value problem that models the problem would be a second-order differential equation.
Let y(t) represent the height of the projectile at time t. The following equation represents the motion of the projectile:
y''(t) = -g
where g is the acceleration due to gravity.
This is a second-order boundary value problem because it involves the second derivative of y with respect to t.
