A 3.20 kg block is pushed along the ceiling with a constant applied force of 85.0 N that acts at an angle of 55.0 with the horizontal.

The block accelerates to the right at 7.50 m/s2.

Determine the coefficient of kinetic friction between block and ceiling.

Would appreciate some guidance on how the Normal force works in this case
