    Answer: 2.75 m/s

    Explanation:

    Initial velocity of rabbit = 2.00 m/s

    Final velocity of rabbit = ? (let unknown be Z)

    Time taken for rabbit = 1.50 seconds

    Acceleration of the rabbit = 0.5 m/s^2

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

    i. e Acceleration = (Final Velocity - Initial velocity) / Time taken

    0.50 = (Z - 2.00) / 1.50

    Make (Z - 2.00) the subject formula

    (Z - 2.00) = 0.50 x 1.50

    Z - 2.00 = 0.75

    Z = 0.75 + 2.00

    Z = 2.75 m/s

    Thus, the final velocity of the rabbit is 2.75 m/s
