A43-n crate is suspended from the left end of a plank. the plank weighs 21 n, but it is not uniform, so its center of gravity does not lie halfway between the two ends. the system is balanced by a support that is 0.30 m from the left end of the plank. how far to the right of the support is the plank

Explanation:

The torque is the force by the distance so to determinate that both torque are the same magnitude so

Solve to d2

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
