| V8424. To Hs.{Lord Ernest Hives - Chair} & EP.{G. Eric Platford - Chief Quality Engineer} from R.{Sir Henry Royce} X.1725 X.3923 X.718. R1/M28.8.23. Perhaps one of you could give the information to say in what distance a car of the type of 6.EX could be pulled up from 15, 20 and 26 m.p.h. Also what is the rate of acceleration between 20 and 30 m.p.h., in feet per sec. per sec. R.{Sir Henry Royce} ------------------------- Acceleration between 20 and 30 m.p.h is 2.5 ft.per sec2. 20 m.p.h. 12 yds. 26 m.p.h. 20 yds. 15 m.p.h. 7 yds. Rm.{William Robotham - Chief Engineer} | ||
