QUESTION 1 1 points Save Answer Two friends need to displace a sculpture. They place it on a light board 1.5 m long. One friend lifts at one end with a force of 300 N, and the other friend lifts the opposite end of the board with a force of 160 N. The board is perfectly horizontal. Where along the board is the sculpture center of gravity located? (Tip: The horizontal board has no mass). 0.52 m from the 300 N end O 1.0 m from the 300 N end O 1.2 m from the 400 N end Right at the center of the board

Explanation / Answer

The sculpture must weigh (300 + 160)N = 460 N

Measure from the 300 N force:
M = 0 = 160N*1.5m - 460N*x
x = 0.52 m

0.52 m from the 300 N end
