Q: The two-dimensional motion of a particle is defined by the relations r = 6 (4 - 2e- t) and θ = 2(2t + 4e- 2t), where r is expressed in feet, t in seconds, and θ in radians. Determine the velocity and the acceleration of the particle
(a) When t = 0,
(b) As t approaches infinity. What conclusions can you draw regarding the final path of the particle?
