Question 1
Calculate the time dilation for a spaceship moving at 80% the speed of light for a trip of 5 years in its frame. What would a stationary observer note?
💡 Hint: Use the time dilation formula and remember to square the speed!
Question 2
Two observers are moving towards each other at 70% the speed of light. Calculate their combined relativistic momentum based on an object's mass of 2 kg with respect to one observer.
💡 Hint: Consider the formula for relativistic momentum!
