What will be the normal pressures at A and B

Given answer must be P= 330 lb

NA= 82.5 lb

NB= 517.5Ib

2. The coefficient of kinetic friction under the sliding
supports at A and B in figure is 0.30. What forces P will
give the 600 lb door a leftward acceleration of 8.05 ft/s²?
What will be the normal pressures at A and B?
