In the apparatus shown in Fig. 4.38, m1 = [COLOR=#000000]1.9[/COLOR] kg, 
= [COLOR=#000000]40[/COLOR]°, and the coefficients of static and kinetic friction between m1 and the inclined plane are 0.30 and 0.20, respectively.

INDENT What is m2 if both masses are at rest?
between kg and kg
(b) What is m2 if both masses are moving at constant velocity? Neglect all friction.
between kg and kg[/INDENT]
