Puck a, of inertia m, is attached to one end of a string of length ℓ/2, and the other end of the string is attached to a second pivot so that b is also free to revolve. in each case, the puck is held as far as possible from the pivot so that the string is taut and then given an initial velocity v perpendicular to the string. a. how does the magnitude of the angular momentum of puck a about its pivot compare with that of puck b about its pivot? b. how does the rotational kinetic energy of a compare with that of b?

6/12=1/2

step-by-step explanation:

the bal will not change its velocity.

does anyone know or what?

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
