Layla and Kai place a steel ball on a bench
They can apply two forces of magnitude 3.0N and 4.5N to the ball
The direction of the forces can be changed
How should they direct the two forces to produce the maximum acceleration of the ball?
Calculate this maximum acceleration

Maximum superposition of forces is when you directly add or subtract them.

Consider Newtons 2nd which states F = MA

When you pair those two statements, you should be able to find it.

Have you not been given the mass of the steel ball?

No aha I put the full question above and that is why I am so confused.

Impossible to work out the mass/acceleration if you're just given the forces, need more

It's impossible to answer without the mass of the ball, or any sort of physical parameters behind it, then :-;

Yes, I thought that. It's strange since it's a OCR sample paper which my teacher gave me.
Thankyou
