A girl pulls on a 25 kg wagon with a force of 35 N. The wagon's wheels have a force of friction on them, with a magnitude of 10 N. What is the acceleration of the wagon?

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.
