Velocity when acceleration is half-Olympiad Problem

  • #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.
