Homework Equations
The Attempt at a Solution
FgsinΘ=mgsinΘ=3.8*9.81*sin38.4°=24.04
FgcosΘ=mgcosΘ=3.8*9.81*cos38.4°=28.49
This is from an online assignment. The second equation should've given me the correct value, but when I input the answer, the system tells me it's incorrect. Could anyone enlighten me on this situation? Maybe I'm doing something wrong. Please I would appreciate a quick reply. Thank you.
