Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A spaceship crew experiences a time dilation where 1 year passes for them, calculate how much time passed on Earth if they traveled at 0.87c.

💡 Hint: Remember to calculate γ first and then apply it to the proper time.

Challenge 2 Hard

The lifespans of certain particles can be altered based on speed. If a particle normally decays after 3.5 μs at rest, how long could it appear to last if it moves at 0.99c?

💡 Hint: Apply the Lorentz factor after calculating it with the given speed.
