1. The problem statement, all variables and given/known data A(n) 43 kg block is pushed along the ceiling with a constant applied force of 560 N that acts at an angle of 67◦ with the horizontal, as in the figure. The block accelerates to the right at 4.5 m/s2. The acceleration of gravity is 9.8 m/s2 . What is the magnitude of the normal force the ceiling exerts on the block? Answer in units of N. 2. Relevant equations F=ma Fn = mg 3. The attempt at a solution I tried to find Fn = mg = 560sin67, it didn't work any ideas?
