If you drive a small mini-car with the speed v against an uphill height of 0.30 m. I know that the hill is circular in the top and then a downhill is coming. Between which limits should the speed v be (ie the speed before the car starts rolling up for the hill) so the car will be able to cross the slopes and have full contact with the substrate all the way? Neglecting air resistance and braking friction.
Should I use this formula?
mv ^ 2/2 = mgh - but what speed do I get when I use this?
How do I know between what limits the speed should be? Should I consider Centripetal force?
