    In the figure, two blocks are connected by a string across a pully. m1 sits at rest on a table.
    m1 = 3.4 kg. Use work and energy to find the speed of the m2 = 2.5 kg block just before it hits the floor in each of the following cases.

    * Distance between the floor and m2 = 1.5

    (a) The table is frictionless.

    (b) The coefficient of kinetic friction of the 3.4 kg block is 0.15.
