The length of a skid mark left by a dirt bike depends on several factors, including the speed of the bike, the type of surface it is skidding on, and the condition of the bike's tires.

Assuming a dry dirt surface, a reasonable estimate for the coefficient of friction between the tires and the ground is around 0.5. To calculate the required speed, we can use the following equation:

v^2 = 2μgd

where v is the initial velocity of the dirt bike, μ is the coefficient of friction, g is the acceleration due to gravity (32.2 ft/s^2), and d is the length of the skid mark (50 ft). Solving for v, we get:

v = sqrt(2μgd) = sqrt(2 * 0.5 * 32.2 * 50) ≈ 40.3 ft/s ≈ 27.5 mph

Therefore, the dirt bike would need to be going approximately 27.5 mph in order to leave a skid mark that is 50 feet long on a dry dirt surface with a coefficient of friction of 0.5.

I think we can all agree that the dirt bike/ atv plague is a citywide problem that needs a solution; mainly for the police to stop sitting on their hands and enforce the fucking law. That said, anybody here over the age of 20 was once a stupid, reckless 20 year old. Was what he did dumb? Undoubtedly. Did he “deserve” it? No, of course not…. What he deserved was a stronger and wiser support system; someone (just one person!) to step in and say, “Dude, not a great idea…”.
While we can be angry at the situation as a whole, we can also mourn the loss of life and sympathize with ALL involved.
