The force on the fry is
Explanation:
We can find the force acting on the fry by using Newton's second law:
where
F is the net force on the fry
m is its mass
a is its acceleration
For the fry in this problem,
Therefore, the force exerted on the fry is

Answer:
a) System aceleration:
b) Direction of movement:
The block down the plane when the acceleration is negative. This occur when:
The block up the plane when the acceleration is positive. This occur when:
Explanation:
For the block the move direction is parallel (||) to the plane
(1)
For the block the move direction is vertical (y)
(2)
Both blocks are connected with the same cable, therefore, the tension on the cable and the acceleration is the same for both.
Solving the equation 2 for T:
(3)
replacing (3) in the equation (1)
(4)
solving (4) for a:
