Look up what a gravitational slingshot is. If a 2000 kg object approaches earth head on at 3000 MPH, what is the maximum speed that it could leave with? (you may want to consider this like an elastic collision. Why might it be reasonable to think of this as an elastic collision?)

**Gravitational Slingshot and Elastic Collision Concept**

**Gravitational Slingshot:**
A gravitational slingshot, or gravity assist, is a maneuver used to accelerate a spacecraft by passing it close to a planet or other astronomical body. The spacecraft gains speed by taking advantage of the planet's motion and gravitational pull, effectively "slingshotting" it into a faster trajectory.

**Scenario Analysis:**
- **Object Details:** A 2000 kg object
- **Approach Speed:** 3000 MPH towards Earth

**Problem Statement:**
Determine the maximum speed the object could achieve after using Earth for a gravitational slingshot. Consider why this might resemble an elastic collision.

**Elastic Collision Analogy:**
In an elastic collision, both momentum and kinetic energy are conserved. When an object performs a gravity assist maneuver, its interaction with a planet can be considered analogous to an elastic collision on a grand scale:
- **Momentum Transfer:** The object exchanges momentum with Earth, gaining speed as it swings around.
- **Energy Conservation:** Although the object gains kinetic energy, the planet's movement ensures overall energy conservation within the system.

Understanding gravitational slingshots as akin to elastic collisions can help conceptualize the energy and momentum transfer processes involved.
