I'm sorry to ask again. But I didn't understand your answer. How did you achieve that equation, could you show me? What is \vec{r}? Is it the radius of the ball? Let's say I impose initial conditions as none friction and none air resistance. How will the equation turn out then?
Thank you for...
Hi.
I have two questions which I have been pondering on and I just can't figure it out. Maybe someone could be kind enough to answer the questions?
Q1; Projectile motion: Let's say we dropped a ball from a height called h.
We achieve a velocity v=\sqrt{2gh} . Let's then say that we hit...
