I forgot to introduce the condition that s (braking) should satisfy that (1/2) m * v ^ 2 m * g = 0,

I'm palmetto state armory sitting with a task in which it is stated that the braking force is given by F (braking) = μ * F (thinner), where μ = 1 This I interpret as that F (braking) = μ * m * g By this, I derive a formula for the relationship between braking distance and velocity palmetto state armory v. I assume that you have to use the formula for kinetic energy is given by E (kin) = (1/2), etc. ^ 2 I get this s (braking) = (1/2 ) m * v ^ 2 m * g, but the results are weird and I can not argue that we possibly palmetto state armory calculate a length here.
I forgot to introduce the condition that s (braking) should satisfy that (1/2) m * v ^ 2 m * g = 0, ie. E (kin)-F (braking) = 0 or E (kin) = F (braking), but it was perhaps a little too fun mix. By your comment, I understand that I should go about it this way: s (braking) = E (kin) / F (braking) ... or what?
