A block of mass 7.5 kg is pulled along a horizontal frictionless floor by a cord that exerts a force of 31.0 N at an angle 26.3° above the horizontal. What is the magnitude of the acceleration of the block?

I have nooo clue what to do for this one. Can someone please show me the steps?

Well, the component of force horiontal, doing the pulling is 31cosTheta.

Forcehorizontal= mass* acceleration

solve for acceleration.

Now it asks for the normal force exerted on the mass by the floor. Do I need to use the acceleration for that?
