1. ## I am willing to help you with math/physics/engineering + more

I will help for free, but at the same time, I won't do your assignments for you. I am a senior studying mechanical engineering, so will help anywhere I can. I can also help with any other lower level class like english, chem, etc. if you need help with that. I have chegg, so if you ever just need solutions to stuff, let me know.

If you can post the problem, any relevant formulas you know of, or even the title of the section in your book, that'd be great

2. @bsbll4life could you help me with this physics problem on my homework? I can find the centripetal force but not the coefficient of static friction.

A 2100 kg truck travels around a highway curve whose radius is 250m. The truck travels at 30 m/s. Calculate the centripetal force acting on the truck. This centripetal force is provided by static friction, which prevents the truck from sliding off the highway. What is the minimum coefficient of static friction needed to keep the truck from sliding. The road is flat.

3. @Jules yeah let me get right on it

@Jules I am assuming the picture I took is too large to upload, but I will type it
Friction = mu (mg) = mV^2/R
Mu (9.81*2100) = (2100*30^2)/250
Mu = .367
