A \( 1.0 \mathrm{~kg} \) block is initially at rest on a horizontal frictionless surface when a horizontal force along an \( x \) axis is applied
to the block. The force is given by \( \vec{F}(x)=\left(2.5-x^{2}\right) \hat{\mathrm{i}} \mathrm{N} \), where \( x \) is in meters and the initial position of the block is \( x=0 \). What is the kinetic energy of the block as it passes through \( x=2.0 \mathrm{~m} \) ?
