Signum function and friction

There've been some times where I've seen people including the signum function, $\text{sgn}(v_x)$ in equations of motion to account for the instant when the horitzontal velocity component, $v_x$, chang …

Work-energy theorem in rotational motion

Considering a cylinder of radius $R$, the condition for rolling without slipping is met when $v=\omega R$. What we'll do is basically find how $\omega$ and $v$ vary in time and equate them: To find $\ …
