Disturbed by speeding cars outside his workplace, Nobel laureate Arthur Holly Compton designed a speed bump (called the "Holly hump") and had it Installed. Suppose a 1800-kg car passes over a
hump In a roadway that follows the arc of a cirde of radlus 20.0 m as in the figure below.
(a) If the car travels at 29.4 km/h what force does the road exert on the car as the car passes the highest point of the hump?
magnitude
direction
(b) What is the maximum speed the car can have without losing contact with the road as it passes this highest point?
km/h
A motorcyclist in the Globe of Death, pictured at the start of the chapter, rides in a 2.2-m-radius vertical loop. To keep control of the bike, the rider wants the normal force on his tires at the top of the loop to equal or exceed his and the bike's combined weight. What is the minimum speed al which the rider can take the loop?
Suppose a 1 800-kg car passesover a bump in a roadway thatfollows the arc of a circle ofradius 20.4 m, as in FigureP7.65. (a) What force doesthe road exert on the car as the car passes the highest point ofthe bump if the car travels at 8.94 m/s? (b) What is the maximumspeed the car can have without losing contact with theroad as it passes this highest point?

Sensors in his car havemeasured the acceleration and velocity of the car, as well as all forces acting on it, forvarious times. The driver’s motion can be broken down into the following steps: Step 1:The driver, beginning at rest, accelerates his car on a horizontal road for ten seconds.Sensors show that there is a force in the direction of motion of 6000N, but additionalforces acting in the opposite direction with magnitude 1000N. The mass of the caris 1250kg. Step 2: Approaching the cliff, the driver takes his foot off of the gas pedal(There is no further force in the direction of motion.) and brakes, increasing the forceopposing motion from 1000N to 2500N. This continues for five seconds until hereaches the cliff. Step 3: The driver flies off the cliff, which is 44.1m high andbegins projectile motion.a.
