a. What is the initial v of the cannonball wrt the ground

b.calculate the landing position neglecting air resistance.

c. calculate landing position considering air resistance.

d. calculate landing position if the same event happens on planet x, which is 3 times the Earth's mass and twice its radius. Furthermore, the viscosity of planet X's atmosphere is 1Ns/m^2 and the density of its atmosphere is 1 kg/m^3. Which form of drag is stronger, linear or quadratic. For your landing calculation, ignore the weaker of the drag forces.

I am just starting this and my only question at the moment is, does the fact that the cannon is free to recoil affect the muzzle velocity and there for the landing position of the cannonball? I

I'll add more as I solve it.

Thanks guys,

Matt
