    Which soup can would hit the bottom of an inclined plane first?

    This is probably a very very lame question, as it's probably a very basic concept, but I have been quite ill and missed wednesday through monday's physics lessons. Basically, if I have 2 soup cans- one empty, one with soup in it, and set them on an inclined plane, which will hit the bottom...

    Solving Projectile Motion: How High Will John's Apple Fly?

    Well that's what the question is asking, and I assume that's displacement. Displacement in our book is D= .5(Vi+Vf)t I have Vi(2.4), and Wf would be 0 once it reached the top, but I don't know t. Am I using the wrong formula here? I have no idea what to do... :frown:

    Solving Projectile Motion: How High Will John's Apple Fly?

    Whoops, sorry about the homework help violation...in such a rush to figure this out that I didnt see the rule. I'm pretty sure he wants us to use a Free Fall kinda thing, with an equation like Vf=Vi+2(a)(t), but not all those factors are there. This is basic physics stuff, we're studying like...

    Solving Projectile Motion: How High Will John's Apple Fly?

    Help me please I've been stuck on this problem for an hour now... John throws and apple from a height of 1.3 m with velocity of 2.4 m/s. Will it reach his friend in a treehouse 5 m above the ground? My book gives the answer "No, it will only reach 1.6 m," but I really want to know how to...
