A wedge of mass M lies on a smooth fixed wedge of inclinaion θ. A particle of mass m lies on the wedge of mass M (please refer in the figure attached). All surfaces are frictionless and the distance of the block from the fixed wedge is l.Find
Normal reaction between M and m
the time after which the particle hits the fixed plane
I will try to give you a direction to proceed.
Say M slides down with acc. a.
Considering M as observer forces on m are mg, N and ma (pseudo parallel to incline).
masinθ+N=mg
Considering ground as observer forces on M are Mg, N and reaction force due to fixed wedge.
Mgsinθ+Nsinθ=Ma
Can you try to proceed further.. you can of course post further if you get stuck.
