Calculate the energy possesed by a stone of mass 20g executing SHM of amplitude 1cm and T=4sec

answered-by-expert Expert Answer
Dear student
 
Total energy of a particle executing SHM is; E = (1/2) mω2A2
here, m = 20 g = 0.02 kg; T = 4s;A = 1cm= 0.01m;  ω = ( 2Π/T) = 1.6 per sec
 Plugging in these value in the given formula, energy may be calculated.
Hope this helps
