I was thinking projectile motion but then I ignored that. I think I would need the force exerted by the ball on the canon and vice versa and then apply it. Is this correct?

Got it!

Well you're right. I guess I could use it but it would be more work for me. The question is asking about the canon being pushed back, will projectiles help?

Would using the range formula instead be better?

That puts me at my original problem. I do not know the final velocity or acceleration.

I did not. I faintly understand projectile trajectories. How could I use and apply it?

Sure! As far as the planet question, I decided to use the M = ar^2/G formula. I have every part beside the mass (which I am trying to solve for) and the acceleration. I feel as if the acceleration is what is holding me back of figuring out both problems. But I do not know which formula to use...

Two astronauts are trying to figure out the mass of Mercury and the mass of Neptune. The astronauts decide to hit a 142 g ball with a bat on each planet and see how far it goes. They know the radius of mercury is 2,440 km and the radius of Neptune is 24,622 km. On mercury one astronaut hits the...
