Acceleration at the peak

  1. Jul 6, 2009 #1
    A baseball is thrown upwards. What is the acceleration at the highest point?

    i thought the acceleration would be 0 since velocity at the highest point is 0 and the derivative of velocity is acceleration. Since velocity is not changing, shouldn't acceleration be 0?

    However the answer is supposed to be 9.8 m/s^2 downwards. why is the answer the acceleration of gravity and not 0?

    Velocity at the top is 0. But the rate of change is still 9.8 m/s2 until it hits something, right?
