A block m slides on a smooth wedge M on a smooth horizontal floor. Which acceleration expressions are correct?

Select all that apply

• Option A

  Wedge acceleration A=mg sinθ cosθ/(M+m sin²θ).

• Option B

  Block acceleration relative to wedge a=(M+m)g sinθ/(M+m sin²θ).

• Option C

  If M→∞, the relative acceleration approaches g sinθ.

• Option D

  The wedge acceleration is independent of m.
