A force of \( 10 \mathrm{~N} \) is applied on a block of mass \( 2 \mathrm{~kg} \) at an angle of \( 37^{\circ} \), as shown in the figure. If at \( t=0 \), \( u=0 \), then find the work done by the force in \( 2 \mathrm{~s} \), given that all the surfaces are smooth.
(1) \( 48 \mathrm{~J} \)
(2) \( 64 \mathrm{~J} \)
(3) \( 80 \mathrm{~J} \)
(4) \( 96 \mathrm{~J} \)
