A canon on a warship fires at a fixed angle 45 degrees. In a battle the ship hides behind a 60 m tall hill. a) What is the minimum firing speed needed to clear the hill (Neglect the air resistance)
b) How far should the ship
be from the base of the hill (point mark as B in the diagram) when it fires the cannon?
c) A Spy sends an instant
message indicating that
the enemy ship is 1400
m away from the base
of the hill (point marked
as B in the diagram) on
the opposite side is

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
