It may be impossible to solve without the picture. Therefore, I linked the picture instead of typing the question.

I'm stuck on the third question.
The third question is the following: "What is her acceleration assuming she is already moving in the direction of Ftot? Express your answer in vector form."
Notice that I already solved for her acceleration if she was stationary. Also, I'm assuming friction is disregarded because it accepted my previous answer and I disregarded friction in my calculations.
3. The Attempt at a Solution :
I'm puzzled by the question. If someone could rephrase it or nudge me towards the first step by a question, I'd be grateful. It's already shown in the picture, but I calculated her acceleration to be "a = 0.52i -0.37k" when initially stationary.
