Rope # 1 (joining A to the center post)
is 2.0 meters long. Rope # 2 (joining A
and B) is 1.0 meter long and has a
tension of 5.0 N. Block A is 2.0 kg, and
is moving with a constant speed of 4.0
m/s. This motion is taking place on a
horizontal, frictionless surface.

instant shown.
a) Draw a free body diagram of block
A. Provide your coordinate system,
and show the direction of acceleration,
if any.
b) Find the magnitude of the tension in
rope # 1.
c) Find the magnitude and direction of
the acceleration of block A.
d) Find the magnitude and direction of
the net force acting on block A. e) Find
the magnitude and direction of the net
force acting on B.
f) Find the constant speed at which
block B is moving.
