A \( 1.5-\mathrm{kg} \) block is initially at rest on a horizontal frictionless surface when a horizontal force in the positive direction
\( \mathrm{P} \) of \( x \)-axis is applied to the block. The force is given by \( \vec{F}=\left(4-x^{2}\right) \vec{i} \mathrm{~N} \), where \( x \) is in meter and the initial position of
W the block is \( x=0 \).
The maximum kinetic energy of the block between \( x=0 \) and \( x=2.0 \mathrm{~m} \) is
(1) \( 2.33 \mathrm{~J} \)
(2) \( 8.67 \mathrm{~J} \)
(3) \( 5.33 \mathrm{~J} \)
(4) \( 6.67 \mathrm{~J} \)
