I am reviewing General Physics for the MCAT and have a question regarding kinematics in one dimension. The question reads as follows: A speeding motorist traveling 120 km/h passes a stationary police officer. The officer immediately begins pursuit at a constant acceleration of 10.0 km/h/s. How much time will it take for the police officer to reach the speeder, assuming that the speeder maintains a constant speed? How fast will the police officer be traveling at this time? I am unsure how to solve this problem, conceptually speaking. I converted the mixed units to units compatible with m/s. My calculated values are as follows: Vmotorist = 33 m/s V0cop = 0 m/s V cop = ? Acop = 2.8 m/s2 T = ? I have used the following kinematics equations: V2 = V02 + 2a∆X V = V0 + aT X = X0 + V0T + ½ aT2 I calculated the time it would take the cop to reach 33 m/s and the distance at that time: V= V0 + aT X = X0 + V0T + ½ aT2 33 m/s = (2.8 m/s2)*t = ½ * 2.8 * 11.82 T = 11.8 s = 194.9 m I also calculated the difference in distance between the motorist and the cop at this point (194.5 m) however I am unsure as to whether or not these values are even relevant. Any assistance with the direction I should go in to solve these questions would be greatly appreciated. Thank you!
