Well my name is Alex. I live in Vancouver. Am a avid car nut all of my life. Have raced my 1979 camaro (with cheverra racing parts) at westwood race track. Own a 71 Pantera (needs restoration). Helped friend prep original 289 comp cobra for racing. My favorite car of all time is the GT40. I plan on buy one at some point. Oh:" F delta T" means a force F acting for a period of time, delta t, that causes a change in momentum delta MV M=mass V-velocity. So F(delta)T= (delta)MV
