In a circus act, an 82 kilogram trapeze artist is swinging on a 5.2 meter rope. The Artist starts from rest (from a platform) and swings on the end of the rope. When the artist is on the platform, the rope makes an angle of 18 degree above the horizontal.
A) Find the maximum kinetic energy of the artist?
B) Find the tension in the rope when the rope is vertical?
C) Find the kinetic energy of the artist when the rope makes an angle of 30 degree below the horizontal?
D) Find the radial and tangential components of the acceleration of the artist when the rope makes an angle of 30 degree below the horizontal.
