**1. The problem statement, all variables and given/known data**

A small object with mass 3.20 kg moves counterclockwise with constant speed 6.30 m/s in a circle of radius 4.70 m centered at the origin. It starts at the point with position vector (4.70 i+ 0j ) m. Then it undergoes an angular displacement of 8.00 rad.

What it its position vector?

In what quadrant is the particle located and what angle does its position vector make with the positive x-axis?

What is its velocity?

What is its acceleration?

What total force is exerted on the object?

**2. Relevant equations**

i believe its the kinematics equations just replaced with angular speed and acceleration variables

**3. The attempt at a solution**

honestly..i think i should know how to do this but i cant seem to figure it out

any lil start would help..thanks
