a body of mass 25kg moving at 3ms-1 on a rough horizontal floor is brought to rest after sliding through a distance of 2.5m on the floor calculate the coefficient of sliding friction (g=10.0ms-2

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.
