Homework Statement
A block with mass 10.7 kg is placed on an inclined plane with slope angle 24^\circ and is connected to a second hanging block that has mass 15 kg by a cord passing over a small, frictionless pulley. The coefficient of static friction is 0.47 and the coefficient of kinetic friction is 0.35.
a) What is the normal force on m_1?
b) If the inclined slope is frictionless, what is the acceleration of the 2 masses? Use up the incline as your + x direction.
c) What is the tension in the cord in this case?
d) Assume friction is down the incline. If friction is down the incline and the 2 blocks are not moving, what is the value of friction?
and e) What is the maximum static friction?
Homework Equations
The Attempt at a Solution
a) is easy, knocking out 10.7*9.8*cos(24) = 95.8N
e) is easy, with 95.8N(.47) = 45.0N
the rest, I'm having trouble with and don't know where to begin.
