The force on an object is given by the equation f = ma. in this equation, f is the force, m is the mass, and a is the acceleration. what is the force on an object that has a mass of 540 kg and an acceleration of 2.3 m/s^2?

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
