A block of mass m slides down the incline of a triangular block of mass M. The angle of inclination is [tex]\theta[/tex]. The trianguilar block is free to slide on a horizontal plane. Assume that all surfaces are frictionless. What is the acceleration of the mass M?
The Attempt at a Solution
so basically i want to ask if my answer is correct, as i'm not familiar with this type of problem, i got:
F(horizontal) = mg cos [tex]\theta[/tex] sin [tex]\theta[/tex]
a(M, horizontal) = F(horizontal) / (m + M)
is this right?
