A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 15.5 m/s. The cliff is h = 61.0 m above a flat, horizontal beach as shown in the figure. A student stands on the edge of a cliff with his hand a height h above a flat stretch of ground below the clifftop. The x-axis extends to the right along the ground and the y-axis extends up from the ground to the top of the cliff. The origin O of the coordinate plane is directly below the student's hand where the base of the cliff meets the flat ground. The student throws a stone horizontally rightward with initial velocity vector v0. The stone falls with a parabolic trajectory, hitting the ground with a velocity vector v that points down and right. Vector g points straight down. (a) What are the coordinates of the initial position of the stone? x0 = 0 Correct: Your answer is correct. m y0 = 61 Correct: Your answer is correct. m (b) What are the components of the initial velocity? v0x = 15.5 Correct: Your answer is correct. m/s v0y = 0
