motion in one dimension, Physics

Assignment Help:
an attacker at the base of a castle wall 3.65 m high throws a rock straight up with speed 7.40 m/s at a height of 1.55 m above the ground. (a) will the rock reach the top of the wall? (b) If so, what is the rock''s speed at the top? If not, what initial speed must the rock have to reach the top? (c) Find the change in the speed of a rock thrown straight down from the top of the wall at an initial speed of 7.40 m/s and moving between the same two points. (d) Does the change in the speed of the downward-moving rock agree with the magnitude of the speed change of the rock moving
