    Answer:

    a=vf – vi/t

    vf=final velocity

    vi= initial velocity

    t=time period

    Now The bicycle went from 3ms to 1ms…

    1.. It decelerated

    2… Since it went from 3 to 1… 1 is the final velocity while 3 is the initial Velocity

    Applying the Formula

    a= 1-3/2

    = -2/2

    a= -1ms-²

    Option D
