Problem # p028 |

The two blocks A and B are at rest in the position shown.
Given is the angle : γ = 28° |

If the acceleration of block A is a

NOTE : Block B will stay in touch with the wall and will not rotate.

HINT :

- For block A take the distance between the wall and its left edge as variable describing the location of block A
- For block B take the distance between its lower left point and the floor as a variable describing the location of block B.
- Find the geometric relationship between these two variables and differentiate.
