[SOLVED] Two Kinematics Problems Hello everyone, I am having some trouble with the following two kinematic problems and I would appreciate any help or hints. Thank you! --- 1. Two rugby players are running towards each other. They are 37 m apart. If one is accelerating from rest at [tex] 0.5 m/s^2 [/tex] and the other was already moving at 3.1 m/s and maintains her speed, a) how long before they crunch together? b) how fast was the accelerating player going? My Work : I am unsure of this, but I think I would need to set two equations equal to each other: each equation representative of each of the two rugby players. However, I do not know which equations I would need to set equal to each other. 2. A police car stopped at a set of lights has a speeder pass it at 27.78 m/s. If the police car can accelerate at [tex] 3.6 m/s^2 [/tex], a) how long does it take to catch the speeder? My Work : I think that the concept is the same; I would need to set one equation for the police car and one for the speeder equal to each other.
