Briefly describe the difference between kinetics and kinematics. how may you objectively measure kinetic or kinematic variables? how may you qualitatively measure kinetic and kinematic variables? name a scenario where kinetic variables are most valuable. name a scenario where kinematic variables are most valuable.

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
