For the damped oscillator shown in previous figure, k= 180 Nm^(-1) and the damping constant b is 40 gs^(-1) .Period of oscillation is given as 0.3 s, find the mass of the block . (Assume b is much less than sqrt(km)). Hint :T = 2pi sqrt((m)/(k)) |

Answer» SOLUTION :`T = 2pi sqrt((m)/(K))` `= m = ( T^(2)k)/(4pi^(2))= ( 0.3 xx 0.3 xx 180)/( 4 xx ( 3.14 )^(2)) = 0.4 kg ` |
