Explanation:

Forces on Block A:

Let the x-axis be (+) towards the right and y-axis be (+) in the upward direction. We can write the net forces on mass as

Substituting (2) into (1), we get

where , the frictional force on Set this aside for now and let's look at the forces on

Forces on Block B:

Let the x-axis be (+) up along the inclined plane. We can write the forces on as

From (5), we can solve for N as

Set (6) aside for now. We will use this expression later. From (3), we can see that the tension T is given by

Substituting (7) into (4) we get

Collecting similar terms together, we get

or

Putting in the numbers, we find that . To find the tension T, put the value for the acceleration into (7) and we'll get . To find the force exerted by the inclined plane on block B, put the numbers into (6) and you'll get
