A block of mass 'm' moves on a horizontal rough surface with initial velocity 'v'. The height of the centre of mass of the block is 'h' from the surface. Consider a point 'A' on the surface of sliding

A block of mass 'm' moves on a horizontal rough surface with initial v

1.	A block of mass 'm' moves on a horizontal rough surface with initial velocity 'v'. The height of the centre of mass of the block is 'h' from the surface. Consider a point 'A' on the surface of sliding
Answer» Angular momentum about 'A' is MVH initially Angular momentum of the BLOCK decreases during sliding Torque of the FORCES acting on block is ZERO about A Angular momentum is not conserved about A Answer :A::B::D
