I somewhat figured out that They are apparently. I'm used to solving the inclined versions of these. I wonder why I'm having this much trouble on a horizontal one

Ok , so this gave me an idea ∑Fx = 0 F = 40 N F - Ff + W ( a / g ) = 0 So if I compute again 40 - Ff + 100 ( 8m/s2 / 9.806) I would get a Ff of 121.5827 N divide that by 100 and I get a coefficient of 1.22 Seems pretty large for a coefficient of friction

Weight, so are you saying Weight does not exist on a horizontal movement ?

The inertia naturally resists the motion so it's negative, frictional force too. Weight is multiplied by the cosine of 90 so it's technically zero. Force appears to be going to the right so it's positive. I'm still having trouble why it's a negative value when computed

0.5 (V2 -Vo2) = 2 * a * d ∑Fy = 0 W = 100N N - W = 0 so W =100 N∑Fx = 0 F = 40 N F - Ff - W ( a / g ) - W = 0

Homework Statement Ignore B & C for now The block in the figure reaches a velocity of 40 m/sec in 100 m, starting from rest. Compute the coefficient of kinetic friction between the block and the ground. W = 100N F = 40 N 2. Homework Equations ∑Fy = 0 so Normal Force = Weight ∑Fx =...

Homework Statement Hello everyone. I tried practicing creating up down counters using the J/K FF. I've been using the Synchronized Clock with an up down counter and the simulation seems to be successful based on this circuit on the image However, in the actual circuit in a breadboard using a...

I'm not familiar with the 74HCT. Supposedly, we're not to use them but since the deadline is a week away, I'm seriously tempted to.

I did some digging and found out using Binary to BCD method. Problem is the 85 ICs have been phased out for decades according to some forums. I'm trying to replicate it using a 4 bit adder IC (74LS83) and a comparator circuit gates so it adds 3 whenever the output goes beyond 4. I'm having no...

A group project. Our professor is strangely old fasioned. Anyway, I'm curious about ROMS. Do they need any IC connections? I thought 74LS48 ICs were Binary to BCD ones? Are there more?

So a 3 bit 2 input multiplier has a maximum of 6 bits and the max integer product is 49. Problem is I have no idea displaying it in 2 seven segment displays since the 74LS48 decoder only has 4 inputs and 7 output, only good for a single 7 seg. And we are required only to use ICs which is rather...

Doesn't explain how subtraction works. What I don't get is why does three inputs of 1 yields an output of 1 carry and 1 sum?

I understand the concept of Kmaps, Quine method and forming a logic diagram but I'm lost at forming an equation from an addition and subtraction equation For example: a 2 bit plus a 3 bit binary integer. I would have a 4 bit sum and 3 carries. However, how does one form the appropriate equation...

Homework Statement We are asked to make a subtractor circuit which has a 2 bit, 2 input data. Homework Equations A1A0 _ B1B0 _________________________________The Attempt at a Solution I would have a 3 bit output with one borrow. The problem is I am stuck at this point and am having...
