1.	A spring of force constant 1200 Mm^(-1) Is mounted on a horizontal table as shown in Fig. A mass of 3.0 kg is attached to the free end of the spring, pulled side ways to a distance 2.0 cm and released. Determine the maximum speed of the mass.
Answer» SOLUTION :Here , `k= 1200Nm^(-1), m= 3.0 KG, A= 2.0 cm = 0.02m` Max. SPEED of the MASS will be when it is passing through the MEAN position, which is given by `V_("max")= Aomega=A sqrt((k)/(m))= 0.02 xx sqrt((1200)/(3))= 0.4 ms^(-1)`
