Oh thanks, so we approach this problem using conservation of energy.
let v = initial velocity
We have this at Point Q:
KE = KE' + PE..
1/2mv^2 = 1/2mv'^2 + mgr.
mv^2/r - 2mg = mv'^2/r
We also have Force at point Q:
Fn = Fc = mv'^2/r = mv^2/r - 2mg
Homework Statement
Homework Equations
F_{c} = \frac{mv^{2}}{r}
The Attempt at a Solution
I think the normal force would be the magnitude of vector sum of centripetal force and gravitational force. So I did:
N = \sqrt{(\frac{mv^{2}}{r})^{2} + (mg)^{2}}
However, it isn't one...
I want to find books or published articles authored by famous physicists or mathematicians. This is not because I'm any fan of them, but from my experience, I gained deep understanding by reading math or physics from the one who actually invented it.
My plan is to rebuild my math/physics...
I'm very confuse about the idea of applying Newton's law of forces and torques on rolling body. The book shows that you can separate the situation in rolling into pure transition and pure rotation. However, what I don't get is, for the calculation of Newton's 2nd law of forces on pure...
If 2 object with different masses and different specific heat at different Temperature are put in water that have certain mass and temperature. If the heat loss is count by percent (that is, let's say 20% of heat is lost). Find the final temperature
To solve this problem, I have to first...
