A car is travelling at the top or a semi-circular hill, and at the top of the hill, it is moving exactly at 32 m/s which is exactly the speed needed to just leave the road/hill. If the same car is travelling over a hill which is one quarter as tall (radius is one quarter), what is the maximum speed, in m/s, it can travel before it just starts to leave the hill?

a 1750kg car is parked at the top of a hill with an incline of 12 degrees. Its brakes fail and the car starts rolling down the hill. a) how long will it take for the car to travel 200m and reach the bottom of the hill? (the coefficient of rolling friction between the tires and the road is 0.10) b) what will be its velocity at the bottom?

PLEASE ANSWER CORRECTLY THE CORRECT ANSWER IS 46
A roller coaster cart starts at the top of a quarter circular
hill (no friction) of some radius at a speed of 11.8
m/s. At the bottom of the hill it encounters a
horizontal surface with friction and the coefficient of kinetic
friction is 0.55. It travels over that horizontal surface for 8
meters and encounters a frictionless loop with a radius of 23
meters. If it is to just barely make...
