    Answer: 0.102m/s^2

    Explanation:

    velocity of ball = 6.15 m/s

    Time taken for ball to roll = 1.00 minute

    Convert 1.00 minute to seconds

    (Since 60 seconds = 1 minute, the time taken for ball to roll = 60 seconds

    Acceleration of the ball = ? (Let unknown value be Z)

    Since acceleration is the rate of change of velocity per unit time

    i. e Acceleration = Velocity / Time

    Z = (6.15 m/s / 60 seconds)

    Z = 0.1025m/s^2

    Round Z to 3 significant digits (Z = 0.102m/s^2)

    Thus, the acceleration of the ball is 0.102 metres per second square
