Problem 4: A student standing on a cliff throws a stone from a vertical height of d = 8.0 m above the level ground with velocity vo = 19 m/s at an angle 0 = 22' below the horizontal, as shown. It moves without air resistance. Use a Cartesian coordinate system with the origin at the initial position of the stone. vo Part (a) With what speed, in meters per second, does the stone strike the ground? Part (b) If the stone 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? yes no

Answer all the parts please
Problem 4: A student standing on a cliff throws a stone from a vertical height of
d = 8.0 m above the level ground with velocity vo = 19 m/s at an angle 0 = 22° below the
horizontal, as shown. It moves without air resistance. Use a Cartesian coordinate system with
the origin at the initial position of the stone.
Part (a) With what speed, in meters per second, does the stone strike the ground?
Part (b) If the stone 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?
yes
no
