3. [20 pts] The path of motion of a 8-lb particle in the horizontal plane is described in terms of polar coordinates as r=(3t+1) ft and 0=(2t²-t) rad, where t is in seconds. When t = 5 secs, calculate the (a) position vector, (b) velocity vector, and (c) acceleration vector. Make sure you are using the proper coordinate system and vector notation. Also, determine the magnitude of the resultant force acting on the particle when t=5 secs.
