I am a college student in physics 111. I need help and already am going to tutoring for this class but still got a 50/100 on my first exam

f=ma=71.5*9.8 = 700.7 I know this is not right because he is also going up against gravity but I don't know what else to use for acceleration. I don't know the angle but I assume it is a 90 degree cliff. w = (Fcos90)1380 = 0. But zero is not the correct answer.
