Question

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.

Graph showing horizontal velocity Vx of a disk over time in 2D kinematics. Graph showing vertical velocity Vy of a disk over time in 2D kinematics.

Accepted Answer

r(2s) = 4  î + 5  ĵ (cm)

Answer

r(2s) = 0  î + 3  ĵ (cm)

Answer

r(2s) = 1  î + 1 ĵ (cm)

Answer

r(2s) = 12  î + 18  ĵ (cm)
