A bus starts from rest at a bus stop and accelerates at a rate of 1.12 m/s^2 for 11.0s. It runs at constant speed for 80.0 s and slows at a rate 1.20 m/s^2 until it stops at the next bus stop. (a) What is the maximum speed attained. (b) Find the total distance covered.

  • Physics - ,

    vmax is just after the 11seconds

    vmax= a*t

    distance covered:

    break it up into three times
    accelerating
    constant speed
    deaccelerating.
