1. The problem statement, all variables and given/known data The general idea is a regular car moving at constant velocity (v0) is attempting to ram a race car whose wheels are spinning at a stop light. The race car waits until the last moment to push the gas pedal, accelerating at constant acceleration (a). The time the race car starts to accelerate is t=0 I'm trying to find t max, basically after the race car accelerates, the longest time you have for the car (with Vo) to run into the race car. 2. Relevant equations Vf=Vi + a(Tf-Ti) Sf=Si + Vi(Tf-Ti) + 1/2a(Tf-Ti)^2 Vf^2=Vi^2 + 2a (Sf-Si) 3. The attempt at a solution I'm having a bit of trouble assigning the knowns and unknowns due to no numbers being given, so I'm not sure how to start it.
