    Answer:

    the car must move with the speed

    v = 72.16 m/s

    Explanation:

    As we know that the momentum of the car and truck is same

    so as per the formula of momentum we have

    P = mv

    so we have

    m_1v_1 = m_2v_2

    so we will have

    910 \times 18 = 227 v

    v = 72.16 m/s

    So the car must move with the speed

    v = 72.16 m/s
