Homework Help: Physics.

Posted by Amanda on Friday, October 21, 2011 at 2:20pm.

A mass of m1 = 12 kg is placed on an incline with an inclination angle of 50 degrees, a coefficient of kinetic friction of 0.16, and a coefficient of static friction of 0.89. m1 is tied to a rope which runs parallel to the incline and runs over a pulley to a hanging mass of m2. In order to move m1 up the incline, what is the minimum mass which m2 needs to be in kg?

please help me solve this problem :]
