(b) VX
(c) V
(d) In your notebook, draw a sketch of the problem. Select the direction along the along the vertical
axis (y-axis) that is positive (upwards or downwards). Select the direction along the along the
horizontal axis (x-axis) that is positive (left or right). Select an origin. Draw the vectors for Vo, Vox Voy"
V, Vx, Vy, ax, a¸. Label on your diagram the initial and final positions of the rock x, y, and xƒ‚ Yf.

(i) What are the horizontal and vertical positions of the rock relative to the edge of the cliff at t = 4 s.
Assume that the origin (0,0) for this part is loacted at the edge of the cliff. Enter the positions with
their correct signs.
