An 80-kg quarterback jumps straight up in the air right before throwing a 0.43-kg football horizontally at 15 m/s . how fast will he be moving backward just after releasing the ball? sort the following quantities as known or unknown. take the horizontal direction to be along the x axis. mq: the mass of the quarterbackmb: the mass of the football(vqx)i: the horizontal velocity of quarterback before throwing the ball(vbx)i: the horizontal velocity of football before being thrown(vqx)f: the horizontal velocity of quarterback after throwing the ball(vbx)f: the horizontal velocity of football after being thrownobvioulsy the two massses are known and i assumed the speed of the football after being thrown and possibly before too? so what else am i missing?

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

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
