    Answer:

    Explanation:

    This is a classic Law of Momentum Conservation problem. For us the equation will look like this:

    [(m_yv_y+m_bv_b)]_b=[(m_y+m_b)v_{both}]_a Filling in with our given info:

    [(70.0)(0)+(.40)(10.0)]_b=[(70.0+.40)v_{both}]_a and

    4.0 = 70.4v and

    v = .06 m/s
