2. A spaceship moving 0.80c direction away from Earth fires a missile that the spaceship measures to be moving at 0.80c perpendicular to the ship’s direction of travel. Find the velocity components and speed of the missile as measured from Earth.

Taking the direction of the spaceship as the x-axis.

And the direction of the missile perpendicular to the spaceship's motion as the y-axis.

Velocity of the missile as measured from the earth = (0.8cî + 0.48cj)

Speed of the missile relative to Earth = 0.93c

Explanation:

The solution to this question is presented in the attached image to this answer.

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

atomic = no of protons.

mass number-atomic number = neutron number
