A small disk slides on a very smooth horizontal surface. The variations of the horizontal and vertical components of the disk's velocity are represented in the figure below. At time t = 0, the disk is at the origin. Calculate the disk's position after 2.0 s.

• A. r(2s) = 0 î + 3 ĵ (cm)
• B. r(2s) = 1 î + 1 ĵ (cm)
• C. r(2s) = 4 î + 5 ĵ (cm)
• D. r(2s) = 12 î + 18 ĵ (cm)

Answer: (C)
