oh yeah haha you're right, I messed up in my algebra, thanks!

Homework Statement What is the value of resistance R in the figure, if the current through the battery is 5.0A? Homework Equations V=IR Rt = (1/R1 + 1/R2)^-1 + R3 The Attempt at a Solution Rt = V/I Rt = 2V/5A Rt = 0.4ohms 0.4 = (1/0.5 + 1/R)^-1 + 0.1 R = -5 ohms (the...

i found a formula that works, it is (850N)(1.6m)+(625N)(1m) = (2m)(F) but i don't understand 2 things: 1) why do we use 1.6m and not 0.4m? 2) why must we divide the answer by the length of the bench?

if (850N)(0.4m)+(625N)(1m) is how much weight the right side is holding up...how would you divide the answer by (m) and still get aprox 990N?

So what i did was, divide the bench's own force by 2 because it's being supported by 2 legs, but i used the torque equation r x F to find the force exerted 0.4m from the right side...then added it together to find the overall force on the right leg. however my work seems to be flawed...

Hi, I am stuck on this question... A student(850 N) sits on a 2 m long bench that weighs 625 N. The student is sitting 0.40 m from the right end of the bench. What upward force is exerted by the right support leg of the bench? please help! My attempt: (0.40m)(820N)+(1m)(625N) =...
