Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.

You need to guide a robot from the red dot on the left to the green dot on the right, avoiding the blue walls along the way. units To do this, you must feed it a series of commands of the form "turn degrees and move forward". Angles are measured in degrees, with positive angles turning counterclockwise, and negative angles turning clockwise. All turns are relative to the robot's current direction. The grid marks 1 unit squares. From the red starting dot, with the robot facing directly to the right, issue your commands: (all commands should be given as decimal values) Move 1: Turn 9 Move 2: Turn Move 3: Turn Move 4: Turn degrees and move degrees and move degrees and move degrees and move units forward units forward units forward units forward
