Problem

Two blocks of masses

m_1

and

m_2

are in contact and move together on a horizontal surface that is essentially frictionless. A constant horizontal force

F

is applied to the system. Which of the following gives the magnitude of the acceleration of the blocks’ common center of mass? a)

a=\dfrac{F}{m_1}

a=\dfrac{F}{m_1+m_2}

a=\dfrac{2F}{m_1+m_2}

a=\dfrac{F}{m_1+\dfrac{m_2}{2}}
