A 7000 kg truck travelling at 18.6 m/s, loses it brakes and collides with the rear end of a smaller car in front of it which has a mass of 3000 kg and is travelling in the same direction at 18.5 m/s. If the speed of the front car is increased to 19.82 m/s as a result of the collision, what is the speed of the rear car after the collision?

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

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
