A computational model predicts the maximum kinetic energy a roller coaster car can have given its mass, the speed at the highest point of its journey, and the height of the highest point. The mass is 250 kg, and the highest point of the journey is at 30 m, where the cart is at rest. What is its maximum kinetic energy?
73,500 J
468,750 J
0 J
112,500 J

kinetic energy = 112,500 J

Explanation:

Given:

Mass m = 250 kg

Final velocity v = 30 m/s

Find:

kinetic energy

Computation:

kinetic energy = 1/2[mv²]

kinetic energy = 1/2[(250)(30)²]

kinetic energy = 1/2[225,00]

kinetic energy = 112,500 J

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
