4:26 What's a brother got to do to get a signed gallon of milk?

[@danthetutor2624]

Lmao, I made this so long ago, I forgot about this. That milk is very past its expiration date now.

Hi Dan, you’ve come so far from 16 subscribers. I’ve been waiting patiently for the last 4 years for my signed milk. I hope you haven’t forgotten about me. 😢

I don’t know who you are, but I love this comment

Help me calculate This factory worker pushes a 30kg crate at a distance of 4.5m along a level floor at a constant velocity by pushing horizontally on it, the coefficient if of kinetic friction between crate and floor is 0.25 Find a) The magnitude of force must the worker apple b) How much work is done on crate by this force? c) How much work is done by friction, by normal force, and by gravitational force?

Hey, check out this video. It should help you. kzbin.info/www/bejne/b4DIpnWCr7mmsLM. The only difference is that velocity is constant instead of slowing down, which means that the work can be found by using W=Fd. Also, since it's constant velocity, the frictional force must be equal to the pushing force.

is there any advantage by using this method? when you do it the "traditional" way, you have to get the components of the weight too and they will be in the form of sin/cos which in terms of sin/cos it's the same way you do it here...

[@danthetutor2624]

So both ways work. I prefer the "tilt" method because everything is right/left or up/down. The traditional way where you don't tilt the diagram means that the axes you are using are at an angle - which is fine, but you need to pay attention to your axes.
