    Assuming the bus undergoes constant acceleration, it is given by:

    a = (Vf-Vi) / Δt

    a is the acceleration, Vf is the final velocity, Vi is the initial velocity, and Δt is the elapsed time.

    Given values:

    Vf = 0m/s (slows to rest)

    Vi = 60m/s

    Δt = 10s

    Plug in the values and solve for a:

    a = (0-60) / 10

    a = - 6m/s²

    The bus decelerates at a rate of 6m/s².
