A particle moves in one dimension from rest under the influence of a force that varies with the distance travelled by the particle as shown in the figure. The kinetic energy of the particle after it has travelled \( 3 \mathrm{~m} \) is
(a) \( 4 \mathrm{~J} \)
(b) \( 2.5 \mathrm{~J} \)
(c) \( 6.5 \mathrm{~J} \)
(d) \( 5 \mathrm{~J} \)
