Shooting a cannon ball from a cannon

What do you think would happen to the launches if the mass was decreased?
The object would not travel such a great distance????
What do you think would happen to the launches if the cannon were lifted to the top of a platform?
The object would travel farther?

F = ma

For a given charge of explosive (force), a smaller mass will undergo a greater acceleration. So, what do you think?

Also, recall that the height h = h0 + v0t - 4.9t^2
a higher h0 means it will take longer to come back down, right?
