in 1993 bicyclist rebecca twigg of the united states traveled 3.00 km in 217.347 s suppose she travels the entire distance at her average speed and that she then accelerates at -1.72 m/s2 TO COME TO A COMPLETE STOP AFTER CROSSING THEfinish line hoew long does it take her to come to a stop?




























in 199

  • physics -

    Vo = 3000m / 217.347s. = 13.8 m/s.
    V = Vo + at = 0
    13.8 - 1.72t = 0
    -1.72t = -13.8
    t = 8.0 s.

    Maybe if you payed. Attention in class you wouldn't need to cheat
