Answer:
The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve.

Answer:
T1 = 675 [N] ; T2 = 707.5 [N]
Explanation:
To solve this problem we must draw a free body diagram, where the bird is located, the posts and distances mentioned.
In the attached image we can see the free body diagram with different forces, angles and distances.
By conducting a distance analysis we can find the angles on both sides of the rope relative to the horizontal.
Then we perform a force analysis on the X-axis and the y-axis in order to find the two equations we need to find the stresses in the cables (T1 & T2)
Answer:
They developed a test for poisons in the human tissues
Explanation:
Around the 19th century, Mathieu Orfila and Robert Christison developed important tests that identified poisons in human tissues.
By so doing, they laid the foundation for what is now called forensic toxicology. This science attempts to identify poisons in human tissues especially by way of autopsies and forensic investigation.
Today forensic toxicology has expanded to include alcohol testing techniques as well as testing athletes for intake of performance enhancing substances.
The plane takes 4.76 s to reach the end of the runway
Explanation:
The motion of the airplane is a uniformly accelerated motion (=at constant acceleration), therefore we can solve the problem by using the following suvat equation:
where
s is the distance covered
u is the initial velocity
t is the time elapsed
a is the acceleration
In this problem, we have:
s = 102 m is the lenght of the runway
u = 0 is the initial velocity of the airplane
is its acceleration
Solving for t, we find the time needed to reach the end of the runway:
