1. The problem statement, all variables and given/known data The block shown in figure #1 above has a mass of 4.30 kg. The applied force F has a magnitude of 31.2 N and is directed at 38.0˚ above the horizontal frictionless surface the block in on. What is the magnitude of the normal force that acts on the block? 2. Relevant equations Fnormal = m*g*cos(theta) 3. The attempt at a solution I get 40.2 N. The answer of our solutions page is 22.9N What am I doing wrong?
