A Block of Mass M_b Rests on a Horizontal Surface

question 27

Multiple Choice

A block of mass m_b rests on a horizontal surface and is accelerated by means of a horizontal cord that passes over a frictionless peg to a hanging weight of mass m_w. The coefficient of kinetic friction between the block and the horizontal surface is µ and the tension in the cord is T. The acceleration of the block is given by

• A) T - m_wg)/m_w + m_b).
• B) T/µm_bg + m_b).
• C) T - µm_b)/m_b.
• D) m_wg - T)/m_w.
• E) T/m_b - µm_bg.
