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?
