person stands at the edge of a cliff and throws a pebble horizontally over the edge with a speed of v0 = 15.0 m/s.The pebble leaves his hand at a height of h = 46.0 mabove level ground at tge bottom of the cliff. How long (in s) after being released does the pebble strike the ground below the cliff?.      With what speed (in m/s) and angle of impact (in degrees clockwise from the +x-axis) does the pebble land?
