Physics

To find the resulting acceleration of the block, we first need to calculate the net force acting on it.

 

The forces acting on the block are:

30N to the right (positive direction)

10N to the left (negative direction)

Net Force = 30N − 10N = 20N

 

Then, we can use Newton's Second Law to find the acceleration:

F = ma

Rearranging this gives us:

 

Where

F is the net force (20 N),

m is the mass (4kg).
