Consider a seesaw with masses m1 and m2 on either side Suppo

Consider a seesaw with masses m_1 and m_2 on either side. Suppose that the position of the fulcrum (pivot point) is labeled as the origin,x = 0. Further suppose that the position of each mass relative to the origin is x_1and x_2, respectively. The seesaw will be in equilibrium if + Use this equation for the following problem. Find the missing mass so that the system is in equilibrium. Round the answer to one decimal place. If necessary.

Solution

M1 X1 + M2 X2 =0

M1 *(-12) + 6* 10 = 0

-12 M1 +60 = 0

-12 M1 = -60

divide both sides by -12

M1 = 5 kg

Answer is 5 kg
