A student standing on a cliff throws a pebble from a vertical height of d = 8.0 m above the level ground with velocity vo = 19 m/s at an angle = 23° below the horizontal, as shown. It moves without air resistance. Use a Cartesian coordinate system with the origin at the initial position of the nebble. d Part (a) With what speed, in meters per second, does the stone strike the ground? Part (b) If the pebble had been thrown from the clifftop with the same initial speed and the same angle, but above the horizontal, would its impact velocity be different?
