Conical Pendulum Help?

[Geek]

A conical pendulum consists of a bob of mass 0.3kg attached to a firm string of length 0.67m. The bob rotates in a circle of radius 0.36m, vertically below the point of suspension. Calculate:

 

i) the linear speed of the bob

ii) the period of rotation of the bob

iii) the tension in the string

 

Please help!!!

The first thing you need to calculate is the centripetal force (gravity and angle of the string). Once you calculate that I'll give you another hint if you need one.
