Using kinematic equations with the launch point as the origin, the vertical component of velocity at impact is calculated by applying the known initial velocity, acceleration due to gravity, and the vertical distance traveled. Upward velocity is treated as positive while horizontal velocity remains constant throughout the flight.

The coefficient of restitution quantifies the elasticity of the collision between the projectile and surface. By substituting this coefficient along with the pre-collision vertical velocity into the restitution equation, the vertical component of the post-collision velocity is determined, indicating how much velocity the projectile retains after impact.

Resetting the origin to the impact point simplifies the kinematic analysis for the post-collision trajectory. This approach allows you to apply kinematic equations directly to find maximum height using the post-collision velocity and the condition that vertical velocity equals zero at peak height.

The principle of linear impulse and momentum for a single particle problem solving helps analyze how the collision changes the projectile's momentum. Understanding this principle enables engineers to predict velocity changes during impact and calculate subsequent motion, essential for Mars mission rover experiments.

The kinematic equation v² = u² + 2as is applied with the post-collision velocity as the initial velocity, final velocity set to zero at peak height, and acceleration as negative gravity. Solving for displacement s yields the maximum height reached by the rebounding projectile after collision.

Horizontal velocity remains constant throughout the projectile's flight and does not affect vertical motion or maximum height calculations. Maximum height depends exclusively on the vertical component of velocity and gravitational acceleration, making horizontal velocity irrelevant to determining the peak height reached by the rebounding projectile.

At maximum height, the projectile momentarily stops its upward motion before falling back down. At this turning point, the vertical velocity component equals zero, which is the defining condition used in kinematic equations to solve for the maximum height reached by the rebounding projectile.
