Velocity when acceleration is half-Olympiad Problem

  1. Sep 15, 2013 #1
    Q: The motion of a body is given by the equation dv/dt=6-3v.If the body was at rest at t=0 then:

    The speed is 1m/s when the acceleration is half of the initial value. (True/False)



    My approach:

    At t=0 the acceleration of the particle is 6m/s^2.Therefore,
    3=6-3v

    which gives v=1m/s.
    So I selected 'true'. But the answer is given to be 'false'. What is wrong with my calculation?

    Nothing, the answer model is wrong.
