m1 = 8.0 kg, m2 = 3.0 kg, θ = 37°, and the radius and mass of the pulley are 0.30 m and 0.30 kg, respectively?
a)What is the acceleration of the masses? (Neglect friction and the string's mass.)
________m/s^2
b)If the pulley has a constant frictional torque of 0.030 m·N when the system is in motion, what is the acceleration of the masses? [Hint: Isolate the forces.]
___________m/s^2

Verified answer
a = (m2 g - m1 g sin 37) / ( m1 + m2)
a = (3 * 9.8 - 8 * 9.8 * 0.6018 ) /( 8 + 3 )= -17.781 / 11 = - 1.6164 m/s2
