Coasting due east on your bicycle at 8.0 m/s, you encounter a sandy patch of road 7.4 m across. When you leave the sandy patch your speed has been reduced to 5.5 m/s. Assuming the bicycle slows with constant acceleration, what was its acceleration in the sandy patch? Give both magnitude and direction

  • physics -

    a = (V^2-Vo^2)/2d
    a = (5.5^2-8^2)/14.8 = -2.28 m/s^2.
