It's possible for a determined group of people to pull an aircraft. drag is negligible at low speeds, and the only force impeding motion is the rolling friction of the rubber tires on the concrete runway. in 2000, a team of 60 british police officers set a world record by pulling a boeing 747, with a mass of 200,000 kg, a distance of 100 m in 53 s. the plane started at rest. suppose that μr=0.02. estimate the force with which each officer pulled on the plane, assuming constant pulling force and constant acceleration.

explanation:

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

e/c, where e is its total energy

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
