A 2.5 Kg watermelon is dropped off an 8-meter balcony. What will the watermelon’s velocity be right before it hits the ground?

The watermelon’s velocity right before it hits the ground is 12.52 m/s.

The principle of conservation of mechanical energy states that the total energy of an isolated system is always conserved.

P.E = K.E

mgh = ¹/₂mv²

gh = ¹/₂v²

v = √2gh

where;

The watermelon’s velocity right before it hits the ground is calculated as follows;

v = √(2 x 9.8 x 8)

v = 12.52 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
