Three people are pushing a 200kg sofa to the right with forces of 50N to the right, 75N to the right, and 20N to the left (not sure what is motive is). What is the acceleration of the sofa Group of answer choices

0.53 m/s2 to the right

0.725 m/s2 to the right

Not enough information

correct it is c.) b b

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.
