Homework Statement
A small metallic bob is suspended from the
ceiling by a thread of negligible mass. The
ball is then set in motion in a horizontal circle
so that the thread describes a cone. Calculate
the magnitude of the angular momentum of the
bob about a vertical axisthrough the supporting point.
angle: 29
string length: 2.4 m
mass: 9 kg
Homework Equations
L= r x mv
The Attempt at a Solution
mass is given in the problem
radius can be found by:
(string length) * sin29 = r
I don't know how to find the velocity...do we first have to find the angular velocity and convert that over to linear velocity?
