Incase you were wondering in the problem description, that "30o" was meant to be 30 degrees. I forgot to change that "o" to "degrees".
For Part C, I calculated it to be 331.125N, but am still getting a wrong answer. I know you said it was over 300, is that what you got too?
By the way, the A = 121.0 and B = 12.5 refers to the equation F=A+Bt^2, not Part A and Part B.
Ah, that was the problem. I only put 12 degrees, not 12.462. Thanks!
