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
pivoted in such a way that the ball will move in a vertical circle.
The system is launched from the horizontal position A with an
initial downward speed v0. The ball just reaches point D
and then stops. Calculate v0.

A mass is attached to one end of a massless string, the other
end of which is attached to a fixed support. The mass swings around
in a vertical circle as shown in Fig. 5.36. Assuming that the mass
has the minimum speed necessary at the top of the circle to keep
the string from going slack, at what location should you cut the
string so that the resulting projectile motion of the mass has its
maximum height located directly...
