a car accelerates from rest at a constant rate alpha for some time, after which it decelerates at a constant rate beeta and comes to rest. if the total time elapsed is t, the maximum velocity acquired by the car will be?

  • physics -

    Let maximum velocity be x
    then x/α+x/β=t
    Solving,
    x=t/(1/α+1/β)
    =αβt/(α+β)
