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.
Fn = mg
The Attempt at a Solution
I tried to find Fn = mg = 560sin67, it didn't work
