I must determine the relation between k and the slope of the inclined plane. I am writing at the top of the topic what I have tried, I found g=ksin(θ) this is wrong. I am trying to use the trigonometry of the problem (no sees that??). Can someome really help me to find the relation between k and...
That's wrong. k is related to the slope of the inclined plane and is independent from the weight. If we use Newton's law we have mk=mgsin \theta \Rightarrow k=gsin \theta I must prove this (without using Newton's law).
Homework Statement
Galileo in seeking to discover the laws governing the motion of bodies under the action of their weight, conducted a series of experiments on inclined planes. Choosing as unit of length the distance traveled by the ball the first unit of time, measuring at subsequent time...
I used the small angle approximation where sin\theta\approx\theta and I'm here: a(t)=-\frac{L}{g}\theta(t) where a(t) is the angular momentum in a given time t. How I will find now that T=2\pi\sqrt{\frac{L}{g}}?

We let a ball with mass m to slide down under the influence of his weight the path defined by the chord or the path defined by the arc of the circle until the ball reach the lowest point, as it seems from the picture. In which path the ball will make the shorter time to...
