Homework Statement
Disregarding friction, if a car was rolling down a hill, what would the speed of the car at the bottom of the hill, be dependent on? Either the height of hill, length of hill, rotational inertia or the acceleration due to gravity.
Homework Equations
Without friction wouldn't the length and height of the hill not matter?
Would the answer be different if friction was significant?
The Attempt at a Solution
If the height and the length don't matter then wouldn't it be the acceleration due to gravity?
