# Answer to Question #13370 in Mechanics | Relativity for Shetal Varghese

Question #13370

Suppose you are designing a cart for carrying goods downhill.To maximize the cart speed,should you design the wheels so that their moments of inertia about their rotation axes are large or small,or it does not matter?Explain assuming that the mechanical energy is conserved?

Expert's answer

mgh=mV^2 /2 => that's how we can find maximum speed. it depends only on

gravity and height. So it does not depend on wheels
