two objects with equal mass are collide. calculate the velocity after the collision if ball red is 10m/s and ball blue is 20m/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

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
