Answer:

Step-by-step explanation:
The given equation is :
N=S(P-V)-F ...(1)
We need to solve the above equation for S.
Adding F both sides in equation (1)
N+F=S(P-V)-F+F
N+F=S(P-V)
Dividing both sides by (P-V). So,

So, the above is the expression for S.
As you already written, you have to use Newton's law

where F is the force, m is the mass, and a is the acceleration.
You already know the mass and the force, so you have to solve the equality for the acceleration:
