Air of density p moving woth velocity v striles normally on an inclined surface(having area A) of a wedge of mass m kept on a.horizontal surface. Collisions are perfectly elastic.(No loss of kinetic energy). Minimum coefficient of static friction between wedge and horizontal is ,if wedge is stationary

Answer 1

Answer:

Air of density ρ, moving with velocity v strikes normally on an inclined surface (having area A) of a wedge of mass m kept on a horizontal surface. Collisions are perfectly elastic (No loss of kinetic energy). Minimum coefficient of static friction between wedge and the horizontal surface, for the wedge to be stationary, is

Force imparted to the wedge=ρ*A*v^2

Answer 2

Answer:

it will not move again,

Explanation:

because it block from the mountains
