Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If an object has a proper length of 150 m and moves at 0.4c, calculate its contracted length L and explain the significance of your result.

💡 Hint: Remember to apply the length contraction formula and consider the significance.

Challenge 2 Hard

A rocket moves at 0.95c, and its proper length is 250 m. How contracted is this length? Discuss its implications if measured from another frame.

💡 Hint: Think about how relativistic speeds affect our observations.
