Question

A block of mass 0.6 kg rests on the inclined
surface of a wedge of mass 1.8 kg. The wedge
is acted upon by a horizontal force F and slides on a frictionless surface.
The acceleration of gravity is 9.81 m/s

If the coefficient of static friction between
the wedge and the block is 1 and the angle of
the incline is 23º, find the minimum value of
F for which the block does not slip.
Answer in units of N

Answer 1

how can i solve this?

Answer 2

find the froce of riction by multiplyinf the fn and mg fn =mgcos23

Answer 3

and for x f-mgsin23-and force=ma sub the fn and solve it
