Oh ok, so instead of numbers I should put variables, then substitute back in the end. I usually don't do that unless the problem gives just variables. Thank you and I will change my work-style.

Yea I drew a free-body diagram on paper. I don't understand by what you meant when you said "The first is that you work parametrically, and only substitute for the question values at the very end." Thank you for your help.

Ok I found all the forces acting on the sled. 25Cos20(from the boy)-60Sin15(gravity) -f=0 (constant speed, velocity) f=7.9631 f=un n+25Sin20=60Cos15 n=49.4 [FONT="Arial Black"]u=.1611 Hm I think I calculated wrong last time. Is this right?

You could always say you are freaked out by blood or by surgeries. Also you could say that the hours are bad and when you get married, your relationship will be messed up because you won't have time. That is what is keeping me from being a doctor. I am talking out of my butt right now.

Oh sorry! I didn't know the equations were wrong! I just saw two equations and you needed help to get a third one. I don't know the equations or what they mean. Sorry for your trouble.

Have you told them that you don't want to be a doctor? Come straight up and tell them first if you haven't done so yet. Tell them that you are very passionate for your subjects. If that doesn't work prove to them that you are, by winning math competitions or stuff like that. Don't say that you...

Ok substitute again that W=Fs into P=W/t. This gets P=Fs/t. Got it? To get F by itself we multiply both sides by t, Pt=Fs, and then you divide by s on both sides. Pt/s=F or F=Pt/s.

Homework Statement A boy drags his 60N sled at constant speed up a 15 degree hill. He does so by pulling with a 25N force on a rope attached to the sled. If the rope is inclined at 35 degrees to the horizontal What is the coefficient of kinetic friction between the sled and snow? At the...

Ok I got θi=45+φ/2. Thank you.

Ah this derivative is too hard for me to get. I'll try your second way. Thank you.

Ah, that is bad luck. They still haven't approved the image.

Here's a picture.

Homework Statement A projectile is fired up an incline (incline angle φ) with an initial speed vi at an angle θi with respect to the horizontal (θi > φ). (a.) Show that the projectile travels a distance d up the incline, where d = 2*vi^2*cosθi*sin(θi-φ) / g*cos(φ)^2 (b.) For what value...

Everyone here has helped me so much, so I will do the same. Ok you know that in 20 minutes, the minute hand moves 1/3 of the circle. Therefore it moves 120 degrees. Drawing a picture helps here. Now you have a isosceles triangle with sides 5.5 and vertex angle 120. Solve to get the other side...

Oh got it so, that makes a right triangle with legs 50mag(A-B) and another leg mag(A-B)/2. aTan(1/100)=.5729. Doubling that i get 1.1458 degrees. Right? For the second one I get aTan(1/n). Right? Thanks slider142!
