As stone of mass .m. is projected from a rubber catpult of of length .

1.	As stone of mass .m. is projected from a rubber catpult of of length .l. and cross-sectional area A stretched by an amount .e.. If Y be the young.s modulus of rubber then findthe velocity of projection of stone?
Answer» Solution :STRAIN energy =` 1/2 F.e` As the stone is RELEASED, the strain energy in the catpult appears in the FORM of KINETIC energy of the stone.
