r cos(angular displacement) =i
r sin(angular displacement) =j
3.15m * cos(9.10 rad) = -2.98
3.15m * sin(9.10 rad) = 1.01
(-2.98i+1.01j)m
A small object with mass 4.05 kg moves counterclockwise with constant speed 1.70 rad/s in a circle of radius 3.15 m centered at the origin. It starts at the point with position vector 3.15 m. Then it undergoes an angular displacement of 9.10 rad.
(a) What is its new position vector?
