You're driving north toward the Big I junction between I-25 and
I-40. You take
the exit ramp to the west. As you drive around the exit ramp and
enter the
westbound freeway, approximately in which direction is the friction
force between your tires
and the pavement pointing just as your car starts to point
west.
| a. |
West |
|
| b. |
South |
|
| c. |
East |
|
| d. |
North |
While you are taking turn, friction force is always acting inside the curvature and perpendicular to speed.
Here initially you are driving north and taking turn toward west,
Hence friction force will acts toward south, when your car starts to point west.
Hence option b is correct.

You are driving your car along a flat, curved road; the curve in the road is a segment of a circle with radius 50 meters. (We call this a "radius of curvature"). How fast can the car drive around the curve if the coefficient of static friction between the tires and the road is 1.0 (tires on dry pavement)? What if the coefficient of friction is 0.2 (tires on ice)?
The Big-I in Albuquerque, NM has an exit ramp that takes southbound traffic eastwards. The ramp is a circular arc of radius 56.5 m, and banked at 32o. The posted speed is 45 mph, which allows a car to neither slide up nor down the incline. Show how to determine the coefficient of friction (kinetic or static?) between the road and the car tires. On an icy day when the coefficient of friction is 30% that of the dry road,...
You and a friend both purchase dune buggies. These off-road vehicles are excellent for driving on sand. To test out your new rides, you decide to play a game of cat and mouse in a desert with sand dunes. Both of you start in the same location. You give your friend a head start, then attempt to catch up teo them. To give you a chance, they radio you their coordinates several times You may assume that both dune buggies...
