WebBy re-writing the first equation, we can calculate the speed at which the collision occurs: V f = V 0 2 − 2 a d = 8.2 m e t r e s p e r s e c o n d. (where d = 40 metres minus the reaction distance of 27.1 metres = 12.9 metres). Thus, the impact occurs at about 30 kilometres/hour, probably fast enough to kill Sam.
