Asack of flour of mass m is lifted vertically at a constant speed of v through a height of h. part a) how great a force is required? take the free fall acceleration to be ) how much work is done on the sack by the lifting force? take free fall acceleration to be ) what becomes of this work-this work becomes kinetic energy.-this work becomes potential energy.-this work becomes both kinetic and potential energy-this work becomes heat.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

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
