Schach [20]

Complete Question

Suppose a NASCAR race car rounds one end of the Martinsville Speedway. This end of the track is a turn with a radius of approximately 57.0 m . If the track is completely flat and the race car is traveling at a constant 30.5 m/s (about 68 mph ) around the turn.

Required:

a. What is the race car's centripetal (radial) acceleration?

b. What is the force responsible for the centripetal acceleration in this case?

O normal

O gravity

O friction

O weight

Answer:

question a

       a = 16.32 \  m/s^2

question b

        correct option is option 3

Explanation:

From the question we are told that

   The radius is  r = 57.0 \ m \

    The constant speed at which the race car is travelling is v  = 30 .5 \ m/s

Generally from the question we are told that the track is completely flat so the only force pulling the car to the middle is the frictional force hence the centripetal force is due to the frictional force

    Generally the centripetal acceleration is mathematically represented as

      a = \frac{v^2}{r}

=>    a = \frac{30.5^2}{ 57}

=>    a = 16.32 \  m/s^2

ECONOMICS !!!!
gulaghasi [49]

Answer:

B

Explanation:

Absolute advantage is the capability of a commercial entity to produce goods using fewer resources compared to rivals. Using the same inputs, an entity with an absolute advantage produces a larger output compared to competitors. It means the firm has a lower marginal cost of production. Therefore, its products will have the lowest prices in the market.

Which structures allow for the removal of wastes from the developing fetus?
castortr0y [4]

The fetus relies upon its mother as it develops. These are some of the things it needs:

<span>protection against knock and bumps, and temperature changes oxygen for respiration nutrients (food and water) </span>

The developing fetus also needs its waste substances removing.

The fetus is protected by the uterus and the amniotic fluid, a liquid contained in a bag called the amnion.
