  3. let me put it into simple terms that i understand haha

    u got a force pushing it this way ----> that is 5 N strong

    and a force pushing it this way <---- that is 3 N strong

    so it should be going to the rightat 2 N but since there is friction it is actually less than 2 N!!!! (between 0 and 2 depending on friction)
  4. doesnt seem like it....shrug ur shoulders and scoff at whoever made that question and hope that your scoffing is deserved...cuz if its not...then u just look like a moron ahahah

    I'm no expert but it seems to me that right answer is not present. **shrug**

    Here's the key point: if the block is moving at a constant velocity, what is the net force on it? Carpe Mori pointed out what the two known forces do, so what must the frictional force be? [The answer is among the choices given, and it is not (d).]
  6. o hahah i got is asking for the frictional force not the net force acting on cube.

    dyanamicsolo explained it well enough u should be able to figure it out now

    I believe it would be.

    BTW, you don't need to submit another post to ask this question: you can edit your previous post. Please also don't "bump" threads -- people who are actively helping will check for post updates, so it isn't necessary to noodge them...

    In (some) Internet forum parlance, "bumping a thread" means adding a post for the purpose of moving the thread heading to the top of the listing of active threads in the forum. (I guess if you didn't know what that was, that wasn't why you did it...)

    In any event, a lot of the helpers can view the list of threads they are involved with in their User Control Panel (note the link "User CP" at the top left corner of the forum "page"). If a thread has been added to since the last time they checked, the heading will appear in boldface, so they know right away that someone has responded. (We are [usually] watching out for you here...)
