The radius of curvature for a speed bump is 3m, what is the max. speed a car can make at the top of the bump without losing contact with the bump? If at that speed, the driver were also accelerating or braking, would it change whether the car stayed in contact with the bump?

A college professor who shall remain anonymous rides a Vespa and occasionally goes too fast over speed bumps. If the radius of curvature for a particular speed bump is 4 m, what is the maximum speed the Vespa can make (in miles per hour) at the top of the speed bump without causing the professor to leave contact with the scooter as it goes over the bump? Model the scooter and professor (not quite realistically) as a single object moving...

Disturbed by speeding cars outside his workplace, Nobel laureate Arthur Holy Compton designed a speed bump (called the Holly Humo) and had it installed. Suppose 1000-kg car passes over a hump In a roadway that follows the art of a circle of radius 18.4 m as in the figure below (a) of the car travels at 28.8 km/h what force does the road exert on the car as the carpasses the highest point of the hump? magnitude direction (b) What...

The radius of curvature of a highway exit is r = 95.5 m. The
surface of the exit road is horizontal, not banked. (See
figure.)
If the static friction between the tires and the surface of the
road is ?s = 0.408, then what is the maximum speed at
which the car can exit the highway safely without sliding?

What is the speed, in m/s, of the roller coaster at the top of the loop if the radius of curvature there is 20.0 m and the downward acceleration of the car is 1.50 g?
Modern roller coasters have vertical loops like the one shown in the figure below. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats. What is the speed, in m/s, of the roller coaster at the top of the loop if the radius of curvature there is 20.0 m and the downward...

The Dunc Gray velodrome, a bicycle race track in Sydney, Australia, has a radius of curvature of 85/π m in the turns. The maximum speed clocked there was 80.3 km/hr. (Draw force diagrams to help you analyze the system. Also, you can assume the bike+rider has mass m.) a. If the track were unbanked, what would the coefficient of static friction between the bike tires and track need to be for the bike to make such a turn without slipping?...
