Example Problem - Particle moving in the XY plane ' Position 17 2 {2t '1' + 4t2j'} meters - t in seconds - At time t = 2 5, determine 0 - Radial component of particle's velocity and acceleration . Transverse components of particle's velocity and acceleration Choose the appropriate conversion from Cartesian to Polar. (check all that apply) 0 = tan-1 y tan 0 = r = V/x2+2 i = .2 + y 2 SUBMITExample Problem . Kinematics . Kinematics (cont.) . Givens/knowns . Relate . As functions x(t) = 2t Y (+ ) = 4+ .
