Question from Mary, a parent: if a motorcycle left a 63 foot skid mark before hitting a car how fast was he going? |
Hi Mary,
This calculation is not straightforward and requires more information than you have included. In Math Beyond School on our web site there is an article titled The Police that has some information on the techniques the police use. You should be aware that the units of speed her are kilometers per hour.
I hope this helps,
Penny
