Use Galileo's formula to solve each problem. Round answers to the nearest tenth. The sculpture of American presidents at Mount Rushmore National Memorial is $500 \mathrm{ft}$ above the valley floor. How long would it take a rock dropped from the top of the sculpture to fall to the ground? (Data from www.travelsd.com)

Key Concepts

Acceleration Due to Gravity

Acceleration due to gravity is the constant rate at which objects accelerate when falling freely toward the Earth. In the imperial system, this acceleration is approximately 32.2 ft/s². This value is critical in calculating the time of fall and displacement in free fall problems.

Uniformly Accelerated Motion

Uniformly accelerated motion refers to motion where the acceleration remains constant throughout. This concept underpins the kinematic equations, including Galileo's formula, and is essential for solving problems involving objects moving under constant acceleration, such as free-falling bodies.

Free Fall Motion

Free fall describes the motion of an object solely under the influence of gravitational acceleration, meaning that the only force acting on it is gravity. In such cases, if the object is dropped (starting from rest), the initial velocity is zero, and the displacement over time can be calculated using the kinematic equations.

Galileo's Formula

Galileo's formula relates displacement, initial velocity, acceleration, and time in motion under uniform acceleration. It is typically written as s = ut + ½at² and is used to model free fall motion when air resistance is negligible.
