A massless rod of length l has weights, each of mass m, attached to its ends. The rod is initially put in a horizontal position, and laid on an off-center fulcrum located at a distance b from the rod’s center. The rod will topple.
a) Calculate the total gravitational torque on the rod directly, by adding the two torques.
b) Verify that this gives the same result as would have been obtained by taking the entire gravitational force as acting at the center of mass.

A mass m has a massless hook of length 2L attached to it. The
end of this hook is a massless sticky scoop. This system of mass
and hook is initially at rest. Another mass m flies with speed v1
directly into this scoop, sticks, and the whole thing starts to
move and rotate. Find expressions for the linear and rotational
velocity of the combined object after the first mass is caught.

A massless rigid rod whose length L = 21.0 cm has a ball of mass
m = 0.079 kg attached to one end (see Figure). The other end is
