Consider Two Masses: M₁= 2

Multiple Choice

Consider two masses: M₁= 2.0 kg and M₂ =1.5 kg. Mass M₁ moves on a horizontal surface where the coefficient of kinetic friction m_k = 0.40. Mass M₂ is hanging freely. The two masses are connected by a strong cord of negligible mass that extends over a frictionless pulley. Assuming that the acceleration of gravity is 10 m/s², the acceleration of M₂ is

A) 0 m/s².
B) 2.0 m/s².
C) 10 m/s².
D) 5.0 m/s².
