Question C1 A 110 kg merry-go-round with radius of 0.85 m was accelerated from rest to 12 rad/s in 10 s when you applied a constant torque of 304
Nm on it. Right after it reached 12 rad/s, you immediately jumped on the edge of the merry-go-round platform which is 0.85 m away from
the axis of rotation.
By assuming the friction is the same before and after the jump, calculate
(a) the friction of the merry-go-round
(b) the angular velocity of the merry-go-round the moment you jumped on it. Assume you have a mass of 69.7 kg.
(c) the duration taken for the whole system to come to rest, from the moment you jumped on the merry-go-round.
Question,

Me pl give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:

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.
