Q.1.Find the total mechanical energy in one time period? my sir says that it is (1/2)mw^2A^2 but according to me it should be 1/4mw^2A^2.How?
Q.2.The total mechnical energy of a spring mass system in SHM is E = (1/2)mw^2A^2.Suppose the oscillating particle is replaced by another particle of double the mass while the amplitude A remains the same. The new mechanical energy will be?
