A roller-coaster car has a mass of 1120 kg when fully loaded with
passengers. As the car passes over the top of a circular hill of radius
21 m, its speed is not changing. (a) At the top of the hill, what is the
normal force (using the negative sign for the downward direction) FN
on the car from the track if the car's speed is v = 7.6 m/s? (b) What is
EN if v = 19 m/s? Use g=9.81 m/s².
At an accident scene on a level road, investigators measure a car's
skid mark to be 102m long. The accident was occurred on a rainy
day, and the coefficient of kinetic friction was estimated to be 0.36.
Use these data to determine the speed of the car when the driver
slammed on (and locked) the brakes.
