Use the formula for the height h of an object that is traveling vertically (subject only to gravity) at time $t$ : $$h=-16 t^{2}+v_{0} t+h_{0}$$ where $h_{0}$ is the initial height and $v_{0}$ is the initial velocity; $t$ is measured in seconds and h in feet. A ball is thrown upward from a height of 5 feet with an initial velocity of 11 feet per second. Find its maximum height.

Key Concepts

Kinematic Equations

Kinematic equations describe the motion of objects under constant acceleration, such as gravity. These equations, which relate displacement, velocity, acceleration, and time, are vital for solving problems involving vertical motion, allowing calculation of parameters like the maximum height an object attains.

Vertex of a Parabola

The vertex of a parabola, represented by a quadratic function, is the point where the function achieves its maximum or minimum value. In projectile motion problems, determining the vertex is essential because it directly gives the time and value of the maximum height reached by the object.

Projectile Motion

Projectile motion refers to the movement of objects thrown or propelled into the air, where the only force acting on them is gravity (neglecting air resistance). This concept is crucial for determining key characteristics such as the maximum height and duration of flight when analyzing the vertical component of an object's motion.

Quadratic Functions

Quadratic functions are mathematical expressions in the form ax² + bx + c. In the context of vertical motion under gravity, these functions represent how an object's height changes over time, with the parabolic shape indicating that there is a single maximum (or minimum) value corresponding to the peak height.
