Question A block of mass \( 2 \mathrm{~kg} \) is initially at rest on a horizontal frictionless surface. A horizontal force \( \vec{F}=\left(9-x^{2}\right) \hat{i} \) newton acts on it, when the block is at \( x=0 \). The maximum kinetic energy of the block between \( x=0 \mathrm{~m} \) and \( x=3 \mathrm{~m} \) in joule is
