A 20 kg block (4) rests on a frictionless table;
a cord attached to the block extends
horizontally to a pulley at the edge of the
table. A 10 kg mass (B) hangs at the end of the
cord.
a. Draw and label the force vectors acting on
each object.
b. Calculate the acceleration of the block and
mass.
c. Calculate the tension in the cord.
