0A block of mass \( 2 \mathrm{~kg} \) is free to move along the \( x \)-axis. Initially, it is at rest and from \( t=0 \) onwards it is subjected to a time-dependent force \( F(t) \) in the \( x \)-direction. The force \( F(t) \) varies with \( t \) as shown in the figure. The kinetic energy of the block after \( 4.5 \mathrm{~s} \) is
(a) \( 4.50 \mathrm{~J} \)
(b) \( 7.50 \mathrm{~J} \)
(c) \( 5.06 \mathrm{~J} \)
(d) \( 14.06 \mathrm{~J} \)
