A rock is thrown from the edge of a cliff with an initial velocity vo at an angle e with the horizontal as shown above. Point P is the highest point in the rock's trajectory and point Q is level with the starting point. Assume air resistance is negligible. Which of the following correctly describes the horizontal and vertical speeds and the acceleration of the rock at point P? Horizontal Vertical Speed Speed Acceleration (A) vo cose (B) (C) vo cose (D) vo cos 0 y sine (E) Up cose Which of the following correctly describes the horizontal and vertical speeds and the acceleration of the rock at point Q?
