I'm really having troubles figuring this stuff out. Here's a question and what I've done.. a) Calculate current through R5 b) Determine Voltage across R5 I haven't gotten a) yet so haven't even tried b). I made a crude drawing of the original circuit in mspaint. So... I did a...

I see why I had the wrong answer.. the answer sheet had errors. Sooo frustrating :D

Question: Evaluate the net torque about the pivot point for each of the following. For the third dimension, use a z axis pointing out of the paper. a) a 3 m long, 95 kg uniform beam. theres a picture to go along with it which I will describe as best I anthe 3 m long beams pivot point( P )...

Thanks, I figured it out a while later. got all the net forces and then got the mass and did a = F / m.

Homework Statement Find the acceleration of the block. the block weighs 1250 N. it has a force of 950 N pulling on it at 70 degrees N of W and another force of 1050 N pulling at 50 degrees N of E. This is just a review question at the start of my physics class first year in...

Homework Statement Well I figured out the first problem I had posted so here's a new one :) If two objects of different masses are sliding along a frictionless surface at the same speed and they both slide of the same frictionless surface. which rises to a greater height? I want to say they...

So if the question was "A brick and a feather fall to Earth at their respective terminal velocities. Which object experiences greater force of air friction?" does it depend on their actual size? if you had a feather from a sparrow and a regular sized brick is the brick experiences greater...

Thanks for that link, it helped a lot. Starting to make sense now. I feel pretty confident I can get it now and with a little more practice have it down for tests. - Otis

If you have a slope of 40degrees to the horizontal and a vertical line coming straight down forming a triangle.. how can that vertical line possible be the hypotenuse? there's going to be a 90degree angle where the hypotenuse and horizontal meet up and hypotenuse will be opposite that angle...

An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. He's at rest, so the total force must be equal to the friction force? I want to say the force is 0 but isn't there...

Well, the friction force would equal the applied force because he's not moving anywhere. I'm not sure what it says about the net force. I'm supposed to show some sort of calculations with my answer as well, but not sure what all I'm able to calculate.

Homework Statement A climber of mass 72 kg can stand on a rock sloping at 40degrees to the horizontal. What can you deduce about the coefficient of static friction between his boots and the rock? ________________________________________________________ I'm really lost on this one. His...

Homework Statement A Jet fighter plane is launched from a catapult on an aircraft carrier. It reaches a speed of 42 m/s at the end of the catapult, and this requires 2.0s. Assuming the acceleration is constant, what is the length of the catapult? Am I looking at this correctly...

Thank you, I ended up figuring it all out before seeing this but I appreciate the reply!

Homework Statement If the force of gravity(weight) of a 1.2kg textbook were to be measured at various distances (d) from the Earth's center, the data would appear as follows: Force(weight)[kg*m^2/s^2] 1) 11.8 2) 5.21 3) 1.9 4) 1.0 Distance[m] 1) 6.4 x 10^6 2) 9.6 x 10^6 3) 16 x 10^6 4) 22 x...
