Apulley with radius r and rotational inertia i is free to rotate on a horizontal fixed axis through its center. a string passes over the pulley. a block of mass m1 is attached to one end and a block of mass m2, is attached to the other. at one time the block with mass m1 is moving downward with speed v. if the string does not slip on the pulley, the magnitude of the total angular momentum, about the pulley center, of the blocks and pulley, considered as a system, is given by:
a. (m1 – m2)vr + iv/rb. (m1 + m2)vr + iv/rc. (m1 – m2)vr – iv/rd. (m1 + m2)vr – iv/re. none of the above

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

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
