3 continued. Given v = <-5, 1, 3> and a = <2, 4, -1>, velocity and acceleration vectors. b. Find aNN, the normal acceleration vector. Verify that the normal acceleration vector is orthogonal to the tangential acceleration. c. The curve of a position function can be approximated with an arc of a circle of radius R. If ||v|| Find R, precise to 2 decimal places. v, then R = aN 2% 3. Given v <-5, 1, 3> and a <2, 4, -1>, velocity and acceleration vectors. a. Find a+T, the tangential acceleration. Find the exact component values, not decimal approximations! атт a NN
