This is called Brachistrochrone problem.
The answer is B. The acceleration due to gravity works better in this path, since in this case the ball is accelerated faster in initial stages of its movement,since height of fall vertically in the initial stages helps gathering higher speed.
Add Answer to:
The lighter-colored ball arrives first because: A. The darker-colored ball cannot accelerate well on the flat...

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...

Then set up photogates in location 2 and 3. Measure the diameter (in m) of the metal balls (you will need it for speed calculations). Then, measure the weight (mass) of the ball (in kg). To have a better measurement of the time,...

United Parcel Services (UPS) is a large well known parcel service. The company started as a small business by two teenage boys’ basement in Seattle. Today UPS delivers to more than 200 countries. For the last 15 years UPS is trying to develop a stronger presence is India. In the case presented in class one learned that strategically UPS have formed alliances with well stablished companies that have already footprint in India and other Asian-Pacific countries. As in any good...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...

Once upon a time American physicians had it all. Overcoming modest beginnings, internal divisions, and myriad rivals, during the 20th century doctors in the United States achieved “professional sovereignty” (Starr 1982). They secured extraordinary levels of clinical and financial autonomy, as well as social prestige and public deference, and through the American Medical Association (AMA) exerted substantial political influence over health policy making. Organized medicine had a crucial role in shaping the major institutions of American health care, including private...
