Question

Three objects are situated along the y-axis. Their masses and positions are: An object of mass m1=2.80 kg at position y1=-0.200 m; an object of mass m2=2.40 kg at position y2=3.30 m; and an object of mass m3=3.40 kg at position y3=-3.60 m. Determine the position in m along the y-axis of the center of mass of the objects.

Answer 1

Answer:

2.3600m

Explanation:

Center of masses is the geometric center between the three masses.

three distances are y1 = 0.200m, y2= 3.30m and y3 = 3.60 m, all in meters.

taking average will give us the geometric center between these three points which will be the center of mass of the three masses.

center of mass is at  $\frac{y_1+y_2+y_2}{3} = \frac{0.200+3.1+3.60}{3}=2.3600meters.$
