A body of mass x gram suspended at the 15cm mark of a ruler balanced it at the 30cm mark on a pivot. If the ruler has a mass of 36g and its centre of gravity is 55cmmark, calculate the (i) mass x (ii) distance of the balanced point of the ruler from the zero end when the body is moved to the 25cm mark.​

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.
