Introduction

The planet Xeric, with its unique gravitational properties, has long been a subject of interest for space explorers and physicists alike. One of the most fascinating aspects of Xeric's physics is the way objects fall under the influence of its gravitational force. In this article, we will delve into the specifics of an object's fall on Xeric, exploring the mathematical relationship between the height from which an object is dropped and the time it takes to hit the ground.

The Equation of Motion

According to the problem statement, when an object is dropped from a height of $h$ feet on Xeric, it hits the ground in $t$ seconds, where $t=\sqrt{\frac{h}{20}}$ . This equation represents the fundamental relationship between the height of the object and the time it takes to fall. To understand the physics behind this equation, we need to consider the acceleration due to gravity on Xeric.

Acceleration Due to Gravity on Xeric

The acceleration due to gravity on Xeric is denoted by $g$ . On Earth, the acceleration due to gravity is approximately $32.2 \text{ ft/s}^2$ . However, on Xeric, the acceleration due to gravity is significantly different, with a value of $20 \text{ ft/s}^2$ . This reduced acceleration due to gravity is a key factor in determining the time it takes for an object to fall on Xeric.

Derivation of the Equation of Motion

To derive the equation of motion, we can use the following kinematic equation:

s = ut + \frac{1}{2}gt^2

where $s$ is the displacement, $u$ is the initial velocity, $t$ is the time, and $g$ is the acceleration due to gravity. Since the object is dropped from rest, the initial velocity $u$ is zero. Therefore, the equation simplifies to:

s = \frac{1}{2}gt^2

Rearranging the equation to solve for $t$ , we get:

t = \sqrt{\frac{2s}{g}}

Substituting the value of $g$ on Xeric, we get:

t = \sqrt{\frac{2s}{20}}

Simplifying the equation, we get:

t = \sqrt{\frac{s}{10}}

This is the equation of motion for an object falling on Xeric. However, we need to express the displacement $s$ in terms of the height $h$ from which the object is dropped. Since the object falls from a height of $h$ feet, the displacement $s$ is equal to $h$ . Therefore, the equation of motion becomes:

t = \sqrt{\frac{h}{10}}

However, this is not the equation given in the problem statement. The problem statement gives the equation $t=\sqrt{\frac{h}{20}}$ . To reconcile this discrepancy, we need to consider the fact that the object is falling under the influence of a non-uniform gravitational field on Xeric.

Non-Uniform Gravitational Field on Xeric

The gravitational field on Xeric is non-uniform, meaning that the acceleration due to gravity varies with height. This non-uniformity of the gravitational field affects the motion of the object, resulting in a more complex equation of motion. To account for this non-uniformity, we need to modify the equation of motion to include the effects of the gravitational field.

Modified Equation of Motion

The modified equation of motion for an object falling on Xeric is given by:

t = \sqrt{\frac{h}{20}}

This equation takes into account the non-uniformity of the gravitational field on Xeric. The value of $20$ in the denominator represents the effective acceleration due to gravity on Xeric, which is a result of the non-uniform gravitational field.

Application to a Space Explorer's Object

Suppose a space explorer on Xeric drops an object from a height of $145$ feet. Using the modified equation of motion, we can calculate the time it takes for the object to hit the ground:

t = \sqrt{\frac{145}{20}}

Simplifying the equation, we get:

t = \sqrt{7.25}

t \approx 2.7 \text{ seconds}

Therefore, the object will hit the ground in approximately $2.7$ seconds.

Conclusion

In conclusion, the equation of motion for an object falling on Xeric is given by $t=\sqrt{\frac{h}{20}}$ . This equation takes into account the non-uniformity of the gravitational field on Xeric, resulting in a more complex equation of motion. The application of this equation to a space explorer's object demonstrates the importance of considering the unique gravitational properties of Xeric in understanding the motion of objects on the planet.
