We are doing this for our physics class, and they are very basic, easy questions. But it is worth a lot, and might end up being our final. (We're allowed to get help any way possible)
A cannonball shot from a long-barrel cannon travels faster than one shot from a short-barrel cannon because the cannonball receives greater
a. force
b. impulse
c. both a and b
d. neither a and b
impulse= Ft
F=ma
I think it is just b, instead of c, because I don't think there is a greater force. It doesn't indicate that a greater force is used on the bigger cannon. But the longer barrel gives it more time, therefore a greater impulse, right?
Just having a brain fart. :P And the easier problems get me, because I over-analyze.
