Question

A small metal ball is suspended from the ceil-
ing by a thread of negligible mass. The ball
is then set in motion in a horizontal circle so
that the thread describes a cone.
The acceleration of gravity is 9.8 m/s2.
What is the speed of the ball when it is in
circular motion? Answer in units of m/s.
How long does it take Tperiod for the ball to
rotate once around the axis? Answer in units
of s.

Answer 1

Would it be asking too much for the length of the thread and the angle of the apex of the cone?
