# Time between Asteroidal Impacts Help pls!!

#### Stellar

If someone could help me with this question I would be so grateful

Consider the Astroid belt as a torus surrounding the sun, populated by 1 million astroids, and with an astroid number density N = 2.3*10^-20 astroids / km^3. For an impact parameter S = 0.5km, and an assumed relative collision velocity in the belt of v0= 3km/s, determine the time between inter-asteroidal collisions. State all relevant equations clearly and define all terms.

Stellar,

The interval between inter-asteroidal collisions would be completely random: without any recursive pattern. Even if you would settle for an 'averaged' interval the number of events between increments would likely vary too much to be considered anything consistent.
