Student student standing on a cliff that is a vertical height D= 8.0 m above the level ground throws stone stone with velocity vo= 25 m/s at an angle theta =24 degrees below horizontal. The stone moves without air resistance, use a Cartisian coordinate system with origin at the stones initial position. (A) with what speed, vf in meters per second, does the stone strike the ground? (B) if the stone had been thrown from the cliff top with the same initial speed in the same angle, but above the horizontal, will it impact velocity be different?
