Suppose an object has a velocity of -7 m/s at t=0. What will the velocity be after 4 seconds if the acceleration of the object is +1 m/s^2?

Vf = - 3 [m/s]

Explanation:

To solve this problem we must use the following equation of kinematics.

where:

Vf = final velocity [m/s]

Vo = initial velocity = - 7 [m/s]

a = acceleration = 1 [m/s²]

t = time = 4[s]

Now replacing:

Vf = -7 + (1*4)

Vf = - 3 [m/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
