Question

A pair of blocks of the mass M =30.7 kg, and 2 M are dragged over a rough, horizontal surface by two constant forces of magnitude  F=98.0 N. The angle α = 22.7 ° . The blocks are displaced 7.5 m, and the coefficient of kinetic friction is 0.258.

*for the normal force of the back block I calculated 307N
*for the magnitude of friction experienced on the back block I calculated 79.206N

I need help calculating:
 -the magnitude of the normal force exerted by the floor on the front block?

-the magnitude of the friction force experienced by the front block?

Please help! my homework is due at midnight and I can't figure this out.
