A force of magnitude \( F_{1} \) acts on a particle so as to accelerate it from rest to a velocity \( v \). The force \( F_{1} \) is then replaced by another force of magnitude \( F_{2} \) which decelerates it to rest.
(a) \( F_{1} \) must be the equal to \( F_{2} \)
(b) \( F_{1} \) may be equal to \( F_{2} \)
(c) \( F_{1} \) must be unequal to \( F_{2} \)
(d) None of these
