Consider Two Masses: M₁ = 1

Multiple Choice

Consider two masses: M₁ = 1.4 kg and M₂ = 2.5 kg connected by a strong cord of negligible mass that extends over a frictionless pulley. The masses are placed on surfaces that make angles of 27° and 60° respectively with respect to the horizontal. The coefficient of kinetic friction between the surfaces and the masses is 0.30. Assuming that the acceleration of gravity is 10 m/s², the acceleration of M₁
Is

A) 0 m/s².
B) 1.0 m/s².
C) 2.0 m/s².
D) 3.0 m/s².
