A spaceship moves away from the Earth with a speed of 0.80c. Thespaceship then fires a missile with a speed of 0.50c relative to the spaceship.

Part A

What is the velocity of the missile measured by observers on theEarth if the missile is fired toward the Earth?

Part B

What is the velocity of the missile measured by observers on theEarth if the missile is fired away from the Earth?

the velocity of the missile measured by observers on the Earth if the missile is fired toward the Earth = 0.50 c

the velocity of the missile measured by observers on the Earth if the missile is fired away from the Earth = 0.928 c

Explanation:

According to the addition of relativistic velocities;

Let the velocity toward the earth be negative; then

Let the velocity away from the Earth be positive;

Then:

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
