Question 2 Two cannons separated by 5km face each other on a line crossing the equator, with one cannon facing north and one facing south. The cannons have the same height and are calibrated to launch cannonballs at 45° angle of elevation. (a) Neglecting the Coriolis force, at what velocity should a cannonball be fired at if it is to hit the other cannon? You may take the uniform acceleration due to gravity as 9.80ms-2 (3 marks) (b) The cannons fire simultaneously and their cannonballs collide in the air. Accounting for the Coriolis force, how far east or west is this collision? (3 marks)
