Apologies if this has been asked before. If you could help I'd appreciate it very much thanks. Just over a month ago I was on my moped and stationary facing up a slight incline on a dry road waiting at a pedestrian crossing for a guy to cross over it. Next second I'm watching the guy jump to one side and traveling forward over the crossing. I eventually came to a halt about 15 - 20 feet from where I was waiting. Turns out the guy in the estate car behind me was distracted by his mobile and so just hit me square on. Are there any formulas for working out how fast he was going please? The slight change to the usual dynamics is that in addition to the inertia of the Tarmac and incline the impact crushed part of the moped into the rear wheel thus acting as a brake. Would be great if someone out there can help. Thanks

Yeh sure. Sorry for that. Please forgive my nooby mistake. I posted first where I thought it best then read the new members email asking me to introduce myself. So if a mod can help me out and delete the other post I'd again be very appreciative. No disrespect intenteded. Thanks for the heads up.
