Question

Hi, I am in physics I and I'm trying to understand this word problem. It saids that a 6.0-m uniform board is supported by two sawhorses 4.0m apart. A 32kg child walks on the board to 1.4 m beyond the right support when the board start to tip. 

a.) Find the mass of the board

b.) Then he walks back 0.40m and stands still. Find the forces exerted by the supports at this time. (use the mass found in part a).

 

Please be detailed of how this works. Its a harder problem for me to understand. Thank you!
