A man stands at the edge of a cliff and throws a rock horizontally over the edge with a speed of v, = 21.5 m/s. The rock leaves his hand at a height of h = 44.0 m above level ground at the bottom of the cliff, as shown in the figure. Note the coordinate system in the figure, where the origin is at the bottom of the cliff, directly below where the rock leaves the hand. (a) What are the coordinates of the initial position of the rock? (Enter your answers in m.) Xo = 0 Yo = 44.0 (b) What are the components of the initial velocity? (Enter your answers in m/s.) Vox = 21.5 m/s Voy = 0 v m/s (c) Write the equations for the x- and y-components of the velocity of the rock with time. (Use the following as necessary: t. Assume that v, and v, are in m/s and t is in seconds. Do not include units in your answers.) Vx =21,5 v m/s -9.80
