Question Angular displacement problem

Hey! I'm having trouble relating the info given with the answers they want...
A small object with mass 3.20 kg moves counterclockwise with constant speed 5.70 m/s in a circle of radius 4.90 m centered at the origin. It starts at the point with position vector (4.90i hat + 0 j) m. Then it undergoes an angular displacement of 9.50 rad.
a)What is it's position vector.
b) What is it's velocity?
c) What is it's acceleration?
d) What total force is exerted on the object?

What "answers" do "they" want?

Is this an algebra or calculus based question in rotational kinematics/dynamics?
