How do I calculate velocity of an object if I know its Lorentz factor?

Click For Summary
To calculate the velocity of an object with a Lorentz factor of 2, rearrange the equation γ = 1/sq(1-(v^2/c^2)). By substituting γ with 2 and knowing that c is the speed of light, you can solve for v. The process involves simple algebra, and assistance is available if you show your work. It's important to follow the homework guidelines and report any incomplete submissions. Understanding the rearrangement of the Lorentz factor equation is key to finding the velocity.

The question I have for my physics homework is "What does the velocity of an object need to be if it's Lorentz factor is 2?"
I know the equation for the Lorentz factor is γ = 1/sq(1-(v^2/c^2)) I just don't know how to get the velocity out of it.
I'm a bit of a math and physics noob so that might bit a slight problem aswell! :P Any help is appreciated!

You need to rearrange the equation, you know γ is 2 and c is the speed of light which is constant so you can find v which is the velocity of the object.
 
It is pretty simple algebra, have you attempted to try? Possibly show some work and we can be of more help.

Remember, if a member has not completed the homework template, please report the thread, do not reply to it.

Thank you.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
