Question

Conceptual Questions

1.) Relativity tells us that objects should look skinner from an external perspective while they move, but I have never seen that in person. Why is this so? Conversely, are there any man-made objects that travel fast enough that we can see this result with the naked eye?

2.) It is impossible to go the speed of light, but it is possible for an object to have a KE of 1/2mc². How is this possible? Please include a graph in your answer to help clarify your reasoning.

Please help, ty I'll rate.
