The mechanism above is a harmonic oscillator. It consists of two identical spheres connected by a massless spring. The two masses translate toward and away from each other and the entire system spins about its center of mass. Assume that there is no relative rotation between masses A and B. You may also assume the center of mass of the system has no velocity. Do not model the masses as particles. Do not include friction. Do not include gravity

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.

i think the answer is tomato juice? not entirely sure though
