6. How fast must an object travel for its total energy to be 80% more than its rest energy? C
How fast must an object be going if its rest length is 3.4 times as long as its observed length?
How fast would it have to be going past you in order for it to appear only 5.55 m long? Give you answer as a ratio of the velocity to the speed of light c. Consider a 6.05 m long sports car going past you at great speed.
How fast must an object move in order to have a kinetic energy that is 3.19 times its rest energy? Express your answer as a fraction of the speed of light to three decimal places.
If you have a vertical string instead of a horizontal would the object travel the same distance w/ the same speed? What vectors of forces would be involved?
