| ORIGINAL. TO HS.{Lord Ernest Hives - Chair} & EP.{G. Eric Platford - Chief Quality Engineer} FROM R.{Sir Henry Royce} R1/M28.8.23. X1725 X3923 X718 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 second per second. [Handwritten Response] Acceleration between 20 & 30 m.p.h. R.{Sir Henry Royce} is 2.5 ft per sec^2 20 M.P.H. 12 15 yards 26 M.P.H. 20 25 yards 15 M.P.H 7 8 1/2 yards | ||
