Thanks guys, I got it now. R1,7,6 should be in parallel with R2,5,3,4 not series.

1. Find the equivalent resistance of the circuit as shown in the diagram below; where R1 = 1 Ω, R2 = 2 Ω, R3 = 2 Ω, R4 = 4 Ω, R5 = 1 Ω, R6 = 1 Ω, and R7 = 2 Ω. http://img21.imageshack.us/i/prob06v2.gif/ http://img21.imageshack.us/i/prob06v2.gif/Homework Equations R(parallel) 1/R(total) = 1/R1...

Nevermind, this should be in introductory physics :S Sorry guys lol

Homework Statement An infinite number of point positive charges of 2.0 C each are arranged in the following linear configuration with a = 88 cm. Find the electric potential at the point 0 on the scale. (link to image) http://img232.imageshack.us/i/prob02.gif/...

which I found using V= d* (square root of( g/2h))

You're right, and after reworking I found the speed to be 8.38 m/s which gave me the right answer

nevermind got it k1+u1+Wnc = k2 + u2 .5mv^2 + 0 + 0 = 0 + mgy v^2= mgy/.5m v^2= gy/.5 v= 4.15 m/s

Homework Statement A skier (m=61.00 kg) starts sliding down from the top of a ski jump with negligible friction and takes off horizontally. If h = 6.70 m and D = 9.80 m, find H. I already found the velocity as he leaves the cliff to be 29.2 m/s Here's a picture of it...

Wouldn't I need to know the mass to use conservation of energy though?

Homework Statement A bus runs out of fuel as it approaches a hill. If the hill is 0.88 m high, how fast must the bus be traveling in order to coast just to the top of the hill? Homework Equations ? The Attempt at a Solution I'm so stuck and it's drving me crazy can someone please...

Figured that much, but I was hopeful. Could you give me a hint or something, I think I might now the equations I need but my notebook is at my dorm right now and my next class is about to start.

wait do you mean the equation itself or I put in the values wrong?

Homework Statement A 1400 kg block of granite is pulled up an incline that has an angle of inclination θ = 29 ° with a constant speed of 1.13 m/s by a steam winch (see Figure). The coefficient of kinetic friction between the block and the incline is 0.12. How much power must be supplied by the...

nevermind n = m(g + v^2/R)

Homework Statement A pilot, whose mass is 78.0 kg, makes a loop-the-loop in a fast jet. Assume that the jet maintains a constant speed of 105 m/s and that the radius of the loop-the-loop is 0.562 km. What is the apparent weight that the pilot feels (i.e., the force with which the pilot presses...
