A spring of force constant 1200 Nm^(-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.

1.	A spring of force constant 1200 Nm^(-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 :Max. speed of the MASS will be when it is PASSING through the mean position , which is given by `V_("max") = A omega = A sqrt(k/m) =0.02 xx sqrt((1200)/(3)) = 0.4 ms^(-1)`
