Chuck Norris’s roundhouse kick is quite impressive. Assume his foot begins from rest and takes two thirds of a second to swing completely around a 1.1-m-radius circular arc. His foot has a constant angular acceleration for the first third of a second and then zero after that. A. If the angular acceleration is assumed constant for the first third of a second, and then zero after that, what is its magnitude during the first third of a second?
B. What is the foot's tangential acceleration during the first 0.334 seconds?
C. What is the maximum tangential speed his foot obtains?
D. When his foot reaches maximum tangential speed as found in part c, what percent of full rotation does this occur?

What are two different ways you could find the value of a? explain these methods.

Fill in the blanks with the numbers is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance

Write a hypothesis about the effect of increasing resistance on the current in the circuit. use theformat and be sure to answer the lesson question. “how do changes in voltage or resistance affect current in an electric circuit? ”
