physics problem?

Question

A chair of weight 145 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F= 38.0N directed at an angle of 34.0 degree below the horizontal and the chair slides along the floor.

Question: Using Newton's laws, calculate n , the magnitude of the normal force that the floor exerts on the chair.
THanks!

Answer 1

While the force is being applied at 34 degrees below the horizontal:
N = 145 + 38sin34 = 166.249N
