Question 1

What is Physics Problems on Forces and Motion about?

Accepted Answer

The center of mass of the barbell is 0.5 meters from the 10kg side.

To solve this, we use the formula:

xCOM = (m1x1 + m2x2) / (m1 + m2)

Where:
m1 = 10kg (weight on one side) 
x1 = 0m (distance from that side)
m2 = 20kg (weight on other side)
x2 = 1m (distance from that side)

Plugging in:

xCOM = (10kg * 0m + 20kg * 1m) / (10kg + 20kg) 
     = 20kg / 30kg
     = 0.
