Question details

» In 2D, dynamics problems can be solved using one of the following coordinate sys- tem: Cartesian, Polar, and normal-tangential. Their definitions are In Cartesian: ax-x-x and a,-у у r_rë2 v2 In Polar: ar and αθ-u (rag) In normal-tangentail: an- and at - dt where p is the radius of curvature, and vt is the tangential velocity, which is, by definition, identical to the actual velocity of a moving object. Note that in n -t coordinates the normal velocity does not exist, and the normal direction is toward the center of a curvature. The distance between the center and the object is defined as the radius of curvature ρ. If an object of mass m is moving on a circular path of radius R with a constant angular speed cWo, calculate 1. the normal and tangential accelerations: an and a, 2. the radial and angular accelerations: ar and αθ 3. the relationship between ag and a, 4. the relationship between ar and an Clearly show your detailed steps of solution procedures.
