A block of mass \( 2 \mathrm{~kg} \) is placed on a wedge fixed to a
P
truck moving with velocity \( 4 \mathrm{~ms}^{-1} \), as shown in the figure. If the block is at rest with respect to the truck, then the net work done in \( 2 s \) :
(1) \( 0 \mathrm{~J} \)
(2) \( 10 \mathrm{~J} \)
(3) \( 76.8 \mathrm{~J} \)
(4) \( 153.6 \mathrm{~J} \)
