You shoot a bullet with a speed of 0.6c to your right. Then, you get on a magical car and begin to travel to your left with a speed of 0.8c. (c is the speed of light) a. What is the velocity of your magical car relative to the bullet? Explain. b. Looking back at the direction where you previously shoot the bullet, can you observe the bullet now? Explain.

Relativity: Ar-ar- Relativistic addition of velocities: -- Problem 1. A child riding a train throws a ball with speed 2/5 of the speed of light in the +x direction, in the train's reference frame. The train itself is moving at a constant speed of 2/5 in the +x direction with respect to the ground. What is the speed of the ball as observed by someone on the ground? The speed of light is c.

A device that is used to measure wind speed is called an anemometer. When it measures the wind on a moving object the measured value is called the apparent wind. A boat carries onboard an anemometer and measures the apparent wind velocity as 30 km/h, coming from an apparent direction of 15◦ east of north. At that time the boat is traveling at 16 km/h at 55◦ east of north relative to the ground. What is the magnitude and direction...

9.1 Lorentz Contraction Objects traveling at relativistic speeds will appear to a stationary observer as shorter, as- suming that it is parallel to the direction of its motion. Using the equation for Lorentz contraction, find the following, where c is the speed of light: a) A spaceship is traveling with a velocity 0.8c. If it is 200m long in its rest frame (when the object is not moving), how long do you observe it to be? Assume that you can...
