A. The speed of the car and riders (total mass = 350.0 kg) at the top of the first hill, Point A, is 4.00 m/s.
What is the speed at Point B, 5.00 m below Point A.
b. The top of the second hill, Point C, is 8.00 m above Point B. Is the roller coaster moving fast enough to
make it to the top of the second hill?
Calculate the minimum speed required at Point B in order for the rollercoaster to reach the top of the
second hill, Point C.
c.
d.
Did you need to know the mass of the car and
riders in order to answer this question? Explain.

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution. b.)biological evolution states laws that are part of mendel’s theory of genetics. c.)mendel’s genetics replaced darwin’s entire concept of biological evolution. d.)biological evolution is a law that explains why all genetics exist.
