Section-E: Numerical Problems
In the figure shown all the surfaces are frictionless, and mass of the block, m = 100 gram. The block and wedge are held initially at rest. Now wedge is given a horizontal acceleration of 10 m/s2by applying a force on the wedge, so that the block does not slip on the wedge. Then find the work done in J by the normal force in ground frame on the block in 1 s.
