Some particles, such as photons, don't have mass but they still have a momentum. F=ma won't work in these cases.

I can't believe there is even a discussion. Have you ever heard of football, Pauly Shore, coney dogs, corndogs, Gerry Ford, penis enlargement pills, English, BE (Budweiser's new beer with caffeine, ginseng and guarana), Cedar Point, Las Vegas, country music, the clapper, chia pets, sororities...

1hr = 3600s The seconds aren't squared \frac{km}{hr}*\frac{hr}{3600s}*\frac{1000m}{1km}=\frac{m}{s}

That's funny, but I think in this case it would actually complicate the problem.

Figure out the velocity just as the shell clears the cliff. Then treat it as a new problem as if the edge of the cliff were your starting point. From there it's a simple 2d projectile motion problem on flat ground.

There is still mass in space. You sure are pumping out a lot of questions Avgiu.

Don't panic.
