When the shuttle bus comes to a sudden stop to avoid hitting a dog, it decelerates uniformly at 5.3 m/s2 as it slows from 9.5 m/s to 0 m/s.
Find the time interval of acceleration for the bus.

  1. Vf=0
    Vi=9.5m/s
    A=5.3m/s2
    T=?

    Vf=Vi+At

    0=9.5-5.3m/s2
    -9.5=-5.3m/s2(t)

    solve for T

    T=1.8s
