Thanks Will do, thanks.

Thanks for your reply. I'm with you. So, what's the easiest way to draw the free body accurately each and every time if I'm not given those angles (N and mg) and there's a box sitting on an inclined plane or an object on a hill that forms an angle, theta, with the ground or horizontal? I've got...

Sorry if I was vague Here's a diagram if it's viewable... a bit small, but I had to scale it...:biggrin: It's strange, but I have a real problem discerning X and Y components. I know I need to skew the X and Y axis but then I have a hard time with the free body setup with regard to SIN, COS...

Hello - My geometry is rusty and I'm having some difficulty visualizing a question. Picture a box sitting on an inclined plane with an incline angle of 30 degrees from the horizontal (floor). The box is at rest. There is a 10N normal force (perpendicular to horizontal) and a force, F...

Thank you! Unfortunately, I didn't get it worked out in time for the grade, but I'll be ready for the next one that's similar. Thank you for the help!

? Thanks. OK, but if I am to solve for F in the first equation, what is the variable N? And kind of a stupid question, but for the mg part of the equation, is it the 2.00 kg mass X 9.8? Can someone please help a little further, I'm almost there - my calcs are not correct! Thanks

Shed More Light? Well, I'm still not having any luck! Can anyone else shed some light?

Thanks for the info - I'm not sure I follow completely, but I'll be sure to look at your response in detail. So, am I to assume that the kg mass can be multiplied by gravity and that should suffice? I gues it's just 2kg and not N because it's in equilibrium on the incline? The normal force...

Wondering if someone could help me with my last set problem? I've been looking at it for quite some time now. The incoming force on the block is confusing me...as a result, I'm not sure how to set it up. I've worked it with the force parallel to the incline as well as perpendicular - but not as...

There was a relative velocity question where the relatives were divided and then the arccos was taken to determine the angle. It was a sample problem I viewed, hence my deduction. Had something to do with a boat crossing a river with a current and boat speed relative to shore - so I saw some...

Nah, makes perfect sense to me now. It's just a simple projectile - like a bullet fired from a gun with a dropped object - disregarding curvature of the earth, both would hit simultaneously because same y component. I think the time factor with this problem threw me off... thanks for explaining...

Relative Velocity? OK - I'm having problems visualizing a relative velocity problem. Please let me know if I am on the right track... problem involves a jet with initial V of 300 mi/h due east that encounters winds at 100 mi/h in a direction 30 degrees north of east. I need to calculate new...

Ahh yes, you stated that in your response... THANKS! Now I know you're right - and I'm on the right track!

Think the bird falls for 1.12 seconds?

OK, I'll take a look at it. Thanks for pondering it... I really appreciate it!
