You could draw your pendulum costume with the pivot point (ie. the top) of the pendulum at the centre of the pendulum costume.

Then you could use:

forever
point towards [mouse-pointer v]
end

You haven't any pendulum project shared, i think.

As per @Scratch-Minion, draw the pendulum with the top of the pendulum at the centre of the costume.
Draw the rest of it horizontally to the right, rather than down (works better with the script below).
Then this may be along the lines of what you want:

forever
if <mouse down?> then
set [angular speed v] to [0]
point towards [mouse pointer v]
else
change [angular speed v] by ([sin v] of (direction))
turn cw (angular speed) degrees
end
end
