## Homework Statement

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.

## Homework Equations

F=ma

Fn = mg

## The Attempt at a Solution

I tried to find Fn = mg = 560sin67, it didn't work

any ideas?
