1) A cannon is at a castle on a cliff and at a hight of 200 m above the sea level. Thecannon barrel points at an angle of +30.0◦from the horizontal (pointing slightly upwards)and can give a maximum speed to the cannon ball of 70.0 m/s. Ignoring air resistancehow close in the horizontal displacement should a ship be in order for the cannon to beable to hit the ship. (hints: identify the motion, write the equations and calculate firstthe total time the ball is in the air). A ship has some size so we do not need an accuracybetter than 10 m.a. about 6.6 ×102 mb. about 5.3 ×102 mc. about 4.3 ×102 md. about 2.2 ×102 m
