You are exactly right thanks a bunch. I was going mad trying to figure out where i was going wrong.

Here is the actual question. And here is my attempt at a solution In Summary I did the following Found the Equivalence Resistance to Be 5.9 ohms and the Current throughout the entire resistor to be 1.53 Amperes Worked backwards from my resistor simplifications. When the resistors were in...

Normal Force would be the in the horizontal direction. However, how do I get Normal force when I do not know the force of that object in the other direction? I feel as if I need some Force that the user is exerting to find it, but the force that the user needs to exert is what I'm trying to find.

Homework Statement A woman holds a book by placing it between her hands such that she presses at right angles to the front and back covers. The book has a mass of m = 0.75kg and the coefficient of static friction between her hand and the book is μs = 0.59. What is the minimum force she must...

I am fairly new here so I apologize for any mistakes in my post. My question concerning solving a system of equations using Gauss-Jordan Elimination is specifically about different ways to handle a possible constant. Say for instance you have three equations: X1+X2+X3 + 3 = 9 2X1+4X2+X3 =...

Wait... should I be looking for the area of a circle and not the area of a cylinder since the pressure is only pushing down on the surface? So I've gotten force which turns out to be 124071 Newtons, but this is only true if I find it by getting the area of a circle whose diameter is 3inches...

Alright so I've gotten a bit further but still not where I need to be. So I have pressure, diameter, and acceleration and here is the following: Power = energy/time Pressure = Force/area Energy = Force * Distance Force = mass * acceleration I have pressure, I have a distance (from velocity)...

Would my Force be pressure? If so that would mean distance and time was given so : HP = 100psi * 5cm/.1sec That would make things very simple, but I don't think pressure is the force is it? I mean it makes sense that it is a force, but in the context of the equations the class I am in is going...

Homework Statement When gas is burned in a cylinder of an engine it creates a high pressure that pushes a piston. If the pressure is 100psi and it moves a 3 inch in diameter piston a distance of 5cm every .1 seconds. How much horsepower does this action produce?Homework Equations Pressure =...

Homework Statement A 3kg projectilce traveling at 100 m/s is stopped by being shot into an insulated tank containg 100kg of water. If the KE of the projectile is completely convereted into thermal energy, how much will the temp of the water increase in degrees celcius? The standard heat of...

Thanks and yeah I caught that when entering my answer luckily.

Ah I see, so these are the steps to find the equation for g: mgH = 1/2m(v)2 g = (1/2m(v)2)/mH g = 1/2(v)2/H ///because mass cancels out Then I plug the info in g = (1/2(13.72m/s)2) / 8.8m g = (1/2(188.24m2/s2) / 8.8m g = (94.12m2/s2) / 8.8m g = 10.7m/s2 Awesome, this makes sense when I...

So I can set: m(g)8m = 1/2m(13.72m/s) But how does that help me solve for g?

Nothing really. This questions is for an introductory Engineering Class surprisingly (Engineering Problem Solving ENGR1300). I know that potential energy is weight (mass * gravity) * height and that Kinetic Energy is 1/2(mass)(velocity)^2. I also know that energy is Force * distance(or height)...

Homework Statement If a ball is dropped from a height (H) its velocity will increase until it hits the ground (assuming that aerodynamic drag due to the air is negligible). During its fall, its initial potential energy is converted into kinetic energy. If the ball is dropped from a height of...
