Homework Help: physics

Posted by k9 on Sunday, June 26, 2011 at 11:18am.

There is a block on top of an incline plane. The incline is going down to the right. The angle to the right of the 90 is 36.9 degree. There is a force pushing on it from the left.

Find the applied force (F) needed to prevent the block from sliding down the incline; ignore friction. The mass of the block is .5 kg and the mass of the incline plane is 2kg.

Part 2 What is the acceleration of the system?

I have the block as .5 kg. mg = 4.9N Fn = cos 36.9 degrees x 4.9 x .5= 3.92 N
mg sin 36.9 degrees = 2.94 N
I believe acceleration is 5.88 m/s 2 for the block

I am stuck.
