2. A clock has a 10 cm minute-hand. From the 12 mark to 8 mark, for tip of minute hand, calculate in unit-vector notation: (12 pts) a) displacement vector. b) average velocity vector. c) average acceleration vector. d) graphically label ri, rf, and r and indicated the direction of Vave e) graphically label Vi, Vf, and V and indicate direction of aave. f) Calculate the magnitude and direction of aave. Express answers in unit of cm, min. Use a coordinate system with the origin at center of clock, the +x-axis along the 3PM, and the +y-axis along the 12PM mark.
