Question The position (in meter) of a particle of mass \( 1 \mathrm{~kg} \) confined to move along the \( y \)-axis varies with time (in second) as \( y=t^{2}-4 t+5 \). The work done by all the forces acting on the particle during \( t=0 \) to \( t= \) \( 4 \mathrm{~s} \) is
(A) \( 8 J \)
(B) \( 16 J \)
(C) \( 32 J \)
