The rubber cord of a catapult has cross-section area 1 `mm^(2)` and a total unstretched length 10 cm. It is stretched to 12 cm and then released to project a partical of mass 5 g. Calculate the velocity of projection (Y for rubber is `5xx10^(8)N//m^(2)`)

A rubber cord has a cross -sectional area 1 mm^(2) and total un-stretched length 10.0cm . It is stretched to 12.0 cm and then released to project a missile of mass 5.0 g. Taking young's modulus Y for rubber as 5.0xx10^(8) N//m^(2) .Calculate the velocity of projection .
