An oscillator consists of a block attached to spring \( (\mathrm{k}=400 \mathrm{~N} / \mathrm{m}) \), At some time \( \mathrm{t} \), the position (measured from the systems equilibrium location), velocity and acceleration of the block are \( -\mathrm{x}=0.100 \mathrm{~m}, \mathrm{v}=-15.0 \mathrm{~m} / \mathrm{s} \), and \( \mathrm{a}=-90 \mathrm{~m} / \mathrm{s}^{2} \).
The amplitude of the motion and the mass of the block are :-
(1) \( 0.2 \mathrm{~m}, 0.84 \mathrm{~kg} \)
(2) \( 0.3 \mathrm{~m}, 0.76 \mathrm{~kg} \)
(3) \( 0.4 \mathrm{~m}, 0.54 \mathrm{~kg} \)
(4) \( 0.5 \mathrm{~m}, 0.44 \mathrm{~kg} \)
