double d John Smith GreaterTorontoRoyal The second one is "Tales from the Secret Footballer" - it's alright, but not that great. Focuses more on himself and what he plans to do after he retires, still some insightful stuff on the world of football,
like the manager who practiced corners with his team by frisbeeing toast at them in the canteen
From my calculations
I think this is Steve Cotterill. Anyone know for sure?
How did you calculate That?
Simulation of a complete flight motion requires knowledge not only of initial conditions, but also the dependence of all forces and moments experienced by the toast due to its dynamic motion through the air. The constants relating the linear approximations of these forces and moments to angles, velocities and angular velocities are called aerodynamic coefficients. An approximate flight model requires a minimum of ten coefficients denoted below by the symbol C;
Lift force: F = (Clo + Cla a) Arv2/2
Drag force: D =[Cdo + Cda (a – ao)2] Arv2/2
Rolling moment: L = [CLrr + CLpp] Adrv2/2
Pitching moment: M =[CMo + CMqq + CMaa] Adrv2/2
Spindown moment: N = CNrr Adrv2/2
where F and D are the lift and drag forces; L, M, and N and p, q, and r the roll, pitch and yaw moments and angular velocities , respectively; ao the angle of attack at zero lift; A and d the toast area and shape, respectively; v the speed and r the atmospheric density.
∴Cotterill is the only answer possible
