Classical and relativistic number of muons

[jessicah]

Homework Statement

4205m above sea level, count 10⁴ muons during time period, find classical and relativistic number of muons expected at sea level, why did they decide to count as many as 10⁴ muons instead of only 10³?

Homework Equations

N=No exp(-ln (2)t)/ t1/2

Hint: How fast do muons travel? What is their half-life? How much time would it take the muons (according to an observer traveling alongside them) to travel 4205m classically? How about relativistically?
