The Conical Pendulum
A small object of mass m is suspended from a string of length L = 1.8 m. The object revolves in a horizontal circle of radius r with constant speed v and angle = 28°
Find the speed of the object.
i found s=v=2.098.
Find the period of revolution, defined as the time interval required to complete one revolution.
i found it to be ... t=2.53
NOW...
For the conical pendulum described above, determine the following if m = 14.0 kg.
(a) the horizontal and vertical components exerted by the string on the object
(b) the radial acceleration of the object.
for H my equation is
T=ma/sin theta
and to find a=s/t
i take what i found in the previous problem right?
so s=v=2.098
and t=2.53?
and for Fv my equation is T=mg/costheta?
and then for part b...mv^2/r...
but what is r?
OKAY i found everything BUT the HORIZONTAL COMPONENT!
HELP
