Anoter M1 question

A pole-vaulter uses a uniform pole AB of length 4m and mass 4.5kg. She holds the pole horizontallly by placing one hand at one end A of the pole and the other at the point C where AC=70cm. Find the vertical forces exerted by her hands on the pole at A and C.

How do you do this?

Will this kind of question come up in M1? I'm doing Edexcel by the way. I've never done this kind of question before!

moments. take them from the point A and the point C, with the knowledge that the pole is in equilibrium.

How do you do it vertically though, i mean all the weight is the same right? So its different from resolving like a plank or something.
