Question
You are out in space with an extremely precise timing device, measuring the speed of various fast-moving objects. A laser gun is mounted on a spaceship and aimed forward. As the spaceship flies toward you at a speed of 100 million m/s, the laser shines a beam of light toward you.
Determine the speed that would be measured in each of the cases listed below.
I am a little confused with this question. Your help would be appriciated.

As the spaceship flies toward you at a speed of 100 million m/s, the laser shines a beam of light toward you. Determine the speed that would be measured in each of the cases listed below The s laser light as measured in your reference frame of the The speed of the laser gun measured in the spaceship reference frame The speed of the laser gun as measured in your reference frame The speed of the laser light measured in the spaceship reference frame 100 million m/s 100 million m/s 100 millian m/s 200 million m/s 250 million m/s 300 million m/s 400 million m 400 million ms 150 million mis zero sl zero Incorrect.Explanation / Answer
The speed of light is constant for both cases so that is equal to 300 Million no matter what reference frame.
The speed of the gun in the SPACESHIP reference frame is zero because it is mounted on the spaceship.
The speed of the gun in YOUR reference frame is equal to that of the spaceship so 100 million.
So correct answer is : 0, 100, 300, 300
