ROTATIONAL MOTION

What is the x-coordinate of point A in the L-shaped lamina?

• 0
• 1
• 2
• 2.5

Why is the center of mass calculation simplified by dividing the lamina into squares?

• Because squares are easier to draw
• Because the mass becomes zero
• Because each square's center of mass is at its geometric center
• Because it increases accuracy

What is the distance between points O(0,0) and D(1,1)?

• 1 m
• √2 m
• 2 m
• 1.5 m

Which point is at the origin in the L-shaped lamina diagram?

• A(2,0)
• B(2,1)
• C(1,1)
• O(0,0)

What is the mass per unit area of the L-shaped lamina?

• 0.5 kg/m²
• 1 kg/m²
• 1.5 kg/m²
• 2 kg/m²
