A spaceship moving toward Earth with a speed of $0.90 \mathrm{c}$ launches a probe in the forward direction with a speed of $0.10 c$ relative to the ship. Find the speed of the probe relative to Earth.

Key Concepts

Inertial Reference Frames

These are coordinate systems in which objects move at constant velocity unless acted upon by external forces. Understanding inertial frames is crucial in problems involving relative motion, as physical laws, including those governing the addition of velocities, hold equally in any such frame.

Relativistic Velocity Addition

In special relativity, the standard addition of velocities from classical mechanics is replaced by the relativistic velocity addition formula. This formula ensures that the resultant speed never exceeds the speed of light, combining velocities in a way that accounts for the effects of time dilation and length contraction.

Special Relativity

This is the physical theory which asserts that the laws of physics are the same in all inertial frames and that the speed of light is constant in vacuum, regardless of the motion of the source or the observer. It underpins the behavior of objects moving at speeds close to the speed of light.
