just asking because later on i might have questions of geometry because im taking that class , fyi im a jr. in high school and hate math, well at first its alright i understand the equations,problems,formulas,etc. but they keep adding new things or making difficult and well i give up but i have to pass this class so next year ill have algebra 2, in oklahoma u need to have 3 credits of math so i need 3 to graduate and if i want to i can have calculus but maybe i wont take it cus its 2 difficult for me, anyways thats all, later on ill ask questions, and sorry if i type too many details!!!!

A cat rides a merr-go-round tuning with uniform circular motion. At time t1 = 2.00s, the cat's velocity is v1 = (3.00 m/s)i + (4.00 m/s)j, measured on a horizontal xy coordinate system. At t2 = 5.00s, its velocity is v2 = (-3.00m/s)i + (-4.00m/s)j. What are (a) the magnitude of the cat's centeripetal acceleration and (b) the cat's average acceleration during the time interval t2 -t1?

I know that axolotl is the champion of regeneration. If its tail, leg or even heart is cut or damaged, it will grow back within several weeks. I also know that every cell of a plant has the ability to regenerate a new plant. So I wonder in a certain condition, if a leg or other part of an axolotl can regenerate a new one?
