A ball of radius r collides elastically with a smooth step of height h. What is the ratio h/r that maximises the height reached by the ball? In this video we answer this question using a vector-based approach.
Some similar problems:
Minimum velocity for a ball to climb a step: • Ball climbing a step: what is the minimum ...
Minimum force to push a wheel over a step: • Physics problem: pushing a wheel over a step
About me: I studied Physics at the University of Cambridge, then stayed on to get a PhD in Astronomy. During my PhD, I also spent four years teaching Physics undergraduates at the university. Now, I'm working as a private tutor, teaching Physics & Maths up to A Level standard.
