A small object with mass 4.00 kg movescounterclockwise with constant speed 5.20 m/s in a circle of radius 3.80 m centered at the origin. It starts at thepoint with position vector (3.80 + 0 ) m. Thenit undergoes an angular displacement of 8.50 rad.
(a) What it its position vector?
(b) In what quadrant is the particle located and what angle doesits position vector make with the positive x-axis?
(c) What is its velocity?
(d) In what direction is it moving?
(e) What is its acceleration?
(f) What total force is exerted on the object?
