A wedge with mass M rests on a frictionless horizontal table top. A block with mass m is placed on the wedge. There is no friction between the block and the wedge. The system is released from rest.

1. Calculate the acceleration of the wedge.
Express your answer in terms of M, m, [itex]\alpha[/itex], and constant g.
2. Calculate the horizontal component of the acceleration of the block.
Express your answer in terms of M,m, [itex]\alpha[/itex] , and constant g.
3. Calculate the vertical component of the acceleration of the block.
Express your answer in terms of M,m ,[itex]\alpha[/itex] , and constant g.
Answer I got but it was wrong not sure if I'm putting it in right or it's just wrong.
1. -(mgsin2([itex]\alpha[/itex])/2M
