    2.2386 m/s

    Explanation:

    I think you would use the momentum equation.

    m1v1=m2v2

    m1 = mass of the bag (8.5kg)

    v1 = speed of bag (6.9 m/s)

    m2 = mass of bag and cart (26.2 kg)

    v2 = speed of cart and bag

    Plug these numbers all into the equation and you solve for v2 which ends up at 2.2386 m/s
