Solve by difficulty

Two fixed frictionless inclined planes making an angle 30° and 60° with the vertical are shown in the figure. Two blocks A and B are placed on the two planes. What is the relative vertical acceleration of A with respect to B?

In the figure shown the acceleration of A is aA=15i+15j then the acceleration of B is: (A remains in contact with B)

                         

                                       

 

 

 

                     

For no friction to act on a block kept on an accelerating wedge as shown in figure, acceleration of the wedge should be

Acceleration of Block on Smooth Inclined Plane
  1. When an Inclined Plane is at rest

 

                           

R=mgcosθ along with normal to the incline mgsinθ=maalong the incline 

a=gsinθ
 

 

  1. When an Inclined Plane is given Acceleration 'b'

R=mgcosθ+mbsinθma=mgsinθmbcosθa=gsinθbcosθ

* Condition for the body to be at rest relative to the inclined plane.

a=gsinθbcosθ=0b=gtanθ
