1. The problem statement, all variables and given/known data
what value of Fmax gives an impulse of 5.6 N\s?

Picture of graph below

2. Relevant equations

Jx=Integral from t initial to t final of Fx(t)dt

^px=Jx

3. The attempt at a solution
I started by setting 5.6 Ns equal to the integral of the area below the curve but I think I am missing a step. I dont fully understand how you would start a problem like this could someone help me to get on the right track, thanks.

I think you are on the right track.

You started correctly by setting:

$$J_x=\int_{t_i}^{t_f}F_x(t)dt$$

HINT: Next, get the integral in terms of the area.
