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.(adsbygoogle = window.adsbygoogle || []).push({});

Figure http://tinyurl.com/9zcf7uq

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
