A780g, 50-cm-long metal rod is free to rotate about a frictionless axle at one end. while at rest, the rod is given a short but sharp 1000n hammer blow at the center of the rod, aimed in a direction that causes the rod to rotate on the axle. the blow lasts a mere 2.5ms.
what is the rod's angular velocity immediately after the blow? the book gives the answer 8.0rad/s

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

the right answer is 0.3 meters per second
