If you drive fast enough over the crest of a hill your car becomes momentarily airborne. One particular hill can be approximated by part of a vertical circle with a radius of 200 m. How fast should you drive over this hill to just barely lose contact with the road as you crest it?
At the top of the crest of the hill, weight of the car will be acting downwards and centripetal force will be acting upwards.
Let
be the velocity of the car when the car barely lose contact with
the road.
When the car barely lose contact with the road, the centripetal force will be equal to the weight of the car
ANSWER:
=======================
If you drive fast enough over the crest of a hill your car becomes momentarily airborne....
A car drives over the crest of a hill of radius 120m with a speed of 39m/s. Does the car maintain contact with the road? Explain.
A car drives over a hilltop that has a radius of curvature 0.114 km at the top of the hill. At what speed would the car be traveling when it tires just barely lose contact with the road when the car is at the top of the hill? (Give answer to the nearest 0.1 m/s)
A road has a hill with a top in the shape of a circular arc of radius 32.0 m. How fast can a car go over the top of the hill without losing contact with the ground?
A car travels down a straight country road that leads over hills and through valleys. On one particular stretch of road, the car encounters a hill that can be approximated as the top of a circle with a radius rh = 105 m. Later, the car comes to a dip with a radius of curvature rd = 75 m. Assume that the car maintains a constant speed of v = 23 m/s as it goes over the hill and through...
what fraction of your normal weight is your apparent weight as you
crest the hill? in percentage
You're driving your new sports car at 80 mph over the top of a hill that has a radius of curvature of 525 m.
You are traveling on a hilly road. At a particular spot, when your car is perfectly horizontal, the road follows a circular arc of some unknown radius. Your speedometer reads 90.0 km/h, and your apparent weight is 30% larger than usual. Use g-9.80 m/s2 for this problem. (a) Are you at the bottom of a hill or the top of a hill at that instant? the bottom of a hill the top of a hill There's not enough information to...
Dr. C. #2. (PHYS 121 engineering design exercise) You have seen why cars inherently accelerate quicker in a straight line and have better fuel mileage than an SUV with the same engine; it's because of air drag and the smaller frontal area and better drag coefficient of the car. Now let's think about why cars handle (take turns, change lanes and make other quick maneuvers) better than an SUV. We'l1 simplify our analysis by considering a vehicle of mass M...

Game Description: Most of you have played a very interesting game “Snake” on your old Nokia phones (Black & White). Now it is your time to create it with more interesting colors and features. When the game is started a snake is controlled by up, down, left and right keys to eat food which appears on random locations. By eating food snake’s length increases one unit and player’s score increases by 5 points. Food disappears after 15 seconds and appears...
