A particle is acted upon by a force \( F \) which varies with position \( \mathrm{x} \) as shown in figure. If the particle at \( x=0 \)
P
has kinetic energy of \( 25 \mathrm{~J} \), then the kinetic energy of the particle at \( x=16 \) is
(1) \( 45 \mathrm{~J} \)
(2) \( 30 \mathrm{~J} \)
(3) \( 70 \mathrm{~J} \)
(4) \( 20 \mathrm{~J} \)
