In the equation 270= 25cosθ t if assume cosθ to be 0, you will get 270=0! This is not possible. ∴cosθ≠0 and hence you can divide cosθ and get an equation for t. I think you meant t = 270 / (25cosθ) and not t = 270 / (250cosθ):confused:

Please tell me a website where I can find latest research papers in classical mechanics.

The temperature of the sun is so high that the matter exists in plasma state.At such high temperatures electrons are not bound to the atoms.Does it mean that the sun is charged? If the sun is neutral, where do the electrons reside?

Energy -- Can energy be negative? Can energy be negative? If yes,can mass be negative?(since E=mc^2)
