1. The problem statement, all variables and given/known data A speeding car traveling at 20m/s passes a stationary police car, which immediately begins to accelerate at 2.0 m/s. The speeder travels with uniform motion until the police car is along side. How long does it take the police car to catch up to the speeder. Speeder: v1: 20m/s Police Car: v1: 0 m/s a: 2.0 m/s^2 2. Relevant equations v=d/t d=v1*t + 0.5*a*(t^2) 3. The attempt at a solution If figure the displacement between the cars should be 0 when they meet so Ds = displacement of speeder Dp = displacement of police Ds + Dp = 0 (20)t + 0.5(2.0)t = 0 Thats my attempt its a pretty sorry one but I really need help.
