Let's pretend the Qs are actual numbers.

So an unstretched, mass less spring constant Q3 N/m and length Q10 meters is attached between a wall and a mass of Q5 kg. The coefficient of both static and kinetic friction between the mass and the table is Q13. A constant force F is then applied to the resting mass until the mass has moved a distance of S meters, by which time the mass is moving a Q8 m/s. what is the force F in newtons?

i don't know if this is right but i tried it this way:

F= Force of friction+ force of Spring+ net force

F= U(coefficient of friction)mg+kx+ma

but what is x in hooke's law Q 10 or S?

I don't use amplitude, do i have to? What would that be, S, Q10 or a number i would have to solve for??
