A steel strip, clamped at one end, vibrates with a frequency of 20 Hz and a amplitude of 5 mm at the free end, where a small mass of 2 g is positioned. Find
(i) the velocity of the end when passing through the zero position,
(ii) the acceleration at maximum displacement,
(iii) the maximum kinetic energy of the mass.
