Aman hits a ball and provides it with an initial velocity of 5.0 m/s on a rough horizontal surface. due to the surface the ball slows down with an acceleration of 0.5 m/s^2 . when the ball is hit, a dog wihch is 1.0 m behind the man runs with acceleration 1.5 m/s^2 starting from the rest to catch the ball.
a) when does the dog catch the ball?
b)how far away from the dog's initial position, does the dog catch the ball?
c)what is the speed of the ball and the dog when the dog catchesthe ball?

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.
