A horizontal force F=150N is applied to the pulley (m=5kg) which has a massless rope going over it connected to the wall on one end and to the block (m=10kg) on the other. The coefficient of kinetic friction between the ground and the block is (0.40). Assume that there exists a constant vertical force on the pulley which supports its weight.

a.
What are the accelerations of the block and the pulley?
b.
What is the tension in the rope?
We don't need to worry about moment of inertia in this problem because the sum of the torques around the pulley is zero. If you don't know what torque and moment of interia are, don't worry, you'll be learning it within a couple of weeks.
