AP Physics 1mediummcq1 pt

A 2.0 kg child sits 1.5 m from the center of a merry-go-round. A 3.0 kg child sits on the other side. For balance, the second child sits

A.1.0 m from the center

B.2.25 m from the center

C.0.67 m from the center

D.1.5 m from the center

Explanation

Core Concept

Torques balance: (2.0)(1.5) = (3.0)d, so d = 1.0 m.

Correct Answer

A1.0 m from the center
