Homework Help: A locust

  1. Sep 13, 2004 #1
    A locust, extending its hind legs over a distance of 4 cm, leaves the ground at a speed of 340 cm/s. Determine its acceleration, presuming it to be constant.

    When I solved that, got an acceleration of 145 m/s^2 but the answer in the solutions manual is 100 m/s^2.
    I used this formula :
    (V_f)^2=(V_i)^2+2as
    While, s=.04, V_f=3.4 m/s and V_i=0.
    What's wrong ?
