Yeah, let's not go with reason.

So i'm having trouble with this really easy ass problem and i just cant figure out how my calculation is wrong.Here is the problem:
A person pushes horizontally with a force 230 Newtons on a 66 kg crate to move it across a level floor. The coefficient of kinetic friction is 0.35. What is the magnitude of the frictional force? i got this part right - 226.611 N

What is the crate's acceleration (use a "+" to indicate acceleration in the same direction as the applied force F, and a "-" to indicate acceleration opposite to the direction of the applied force F).
for this part I did (230 N - 226.611 N) / 66kg.... but apparently thats not right? any help?

does anyone wanna help with a vector problem? I've been doing this shit all day, and I can't get this one. Niggers.

>implying you wouldn't tap that ass

Butt, both gender love to stare at it.

Why?

Is it because our ancestors are apes that walk on four legs and we stare at each other's butt all day long?

A remnant of evolution? A sign of health? Big butts mean more fat storage and increased probability of survival and raising the young ones during harsh times when food are hard to come by?

what are /sci/s predictions for the next step of human evolution(inb4 they will extinguish)

also will human get those ass pillows because we work so much in a sitting position?
