Un cuerpo de 40 kg de masa se mueve hacia arriba en un plano inclinado de 30º con respecto a la horizontal. sobre el cuerpo actúan las siguientes fuerzas: una fuerza horizontal de 120 n, una fuerza paralela al plano de 200 n favoreciendo el movimiento, una fuerza de fricción de 50 n que se opone al movimiento. el cuerpo se traslada 40 m a lo largo del plano inclinado a velocidad constante. calcular el trabajo de cada fuerza y el trabajo total.

attach the statements so i can answer : )

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

both the fifth and fourteenth amendments of the united states contain a due process clause. while the fifth amendment describes a legal obligation of the federal government to not deprived of life, liberty or property without due process of law, the fourteenth amendment applies the same obligation to the states to guarantee that all of the states provide fair procedures as well.
