A well-thrown ball is caught in a well-padded mitt. If the deceleration of the ball is 2.10*104 m/s2, and 1.85 ms (1 ms = 10-3 s) elapses from the time the ball first touches the mitt until it stops, what was the initial velocity of the ball?

    u = - 38.85 m/s^-1

    Explanation:

    given dа ta:

    acceleration = 2.10*10^4 m/s^2

    time = 1.85*10^{-3} s

    final velocity = 0 m/s

    from equation of motion we have following relation

    v = u + at

    0 = u + 2.10*10^4 * 1.85*10^{-3}

    0 = u + (21 * 1.85)

    0 = u + 38.85

    u = - 38.85 m/s^-1

    negative sign indicate that the ball bounce in opposite directon
