SUMMARY
The discussion focuses on calculating the resultant velocity of two equal velocities of 100 km/h that are oriented at right angles to each other. The correct approach involves using vector addition, specifically applying the Pythagorean theorem. The resultant velocity is determined to be approximately 141.4 km/h, which is derived by multiplying one of the velocities by the square root of 2. This calculation confirms that the resultant velocity increases when two equal vectors are combined at right angles.
