1. The problem statement, all variables and given/known data Drag racing usually involves two cars racing each other over a set distance. Although distances range from 200 m to 1 km, the 400.0 m drag race is the most popular. This race tests a vehicle's acceleration and top speed. Data collected on a race by a dragster- Distance (m) | 20.0 | 400.0 | Time (s) | 0.945| 8.96 | The acceleration of the dragster, from the 20.0 m mark to the 400.0 m mark, is? 2. Relevant equations v= d/t a= (Vf - Vi)/ t 3. The attempt at a solution Vi= d/t = 20.0m/0.945s = 21.16m/s Vf= d/t = 400.0m/8.96s = 44.64 m/s a = (Vf- Vi)/t = (44.64 - 21.16)/ (8.96 - 0.945) = 2.93 m/s2 I know that this isn't right because the answer is supposed to be 1.27 m/s2. But I can't figure out how to solve it to get this answer. If anyone could tell me if I'm using the wrong formula or doing something wrong that would be great.
