1. A rock is thrown off a cliff at an angle of 51 with respect to the horizontal. The cliff is 126 m high. The initial speed of the rock is 24 m/s. (a) Fill in the following: Vo = 24 Vox Voy 24cos(51°)✔✔ = 24sin(51°) m m S m S = S (b) vx remains the same durin (c) vy changes during the mot (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, ay. Label on your diagram the initial and final positions of the rock xo, Yo, and Xfr Yf. (e) How high above the edge of the cliff does the rock rise? Ay= (f) How far has it moved horizontally when it is at maximum altitude? 4x= m m (g) How long after the release does it hit the ground? ground (h) What is the range of the rock? Ax total S m (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.
