A force of \( 10 \mathrm{~N} \) at an angle of \( 37^{\circ} \) and a force of \( 2 \mathrm{~N} \)
\( \mathrm{P} \)
is applied on a block of mass \( 2 \mathrm{~kg} \), as shown in the figure. All the surfaces are smooth. If at \( t=0, u=0 \), then the total work done on the block in \( 2 \mathrm{~s} \) :
\[
\mu=0
\]
(1) \( 20 \mathrm{~J} \)
(2) \( 48 \mathrm{~J} \)
(3) \( 36 \mathrm{~J} \)
(4) \( 64 \mathrm{~J} \)
