Homework Help: physics

Posted by megan on Thursday, March 3, 2011 at 1:22am.

Two blocks, A and B (with mass 50 kg and 100 kg, respectively), are connected by a string, as shown in Figure P5.64. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block A and the incline is ľk = 0.25. Determine the change in the kinetic energy of block A as it moves from C to D, a distance of 19 m up the incline if the system starts from rest.


Angle is 37

So far all I have is Fk = 97.8N

Appreciate it!
