A 4 kg ball moving to the right at 5.0 m/s has an elastic head-on collision with a 2 kg ball that is initially at rest. After the collision the 2 kg ball is moving at 14 m/s. Calculate the final velocity of the 4 kg ball. Be sure your answer accounts for the correct magnitude and direction

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

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
