my answers and the correct answers don't match up. if someone could show me step by step how i should go about solving it that would be koo.

a) What is the maximum static friction force that can be placed on the 10 kg mass? What force F produces that force on the 10 kg mass?

b) Using F = ma where m is the total mass, you should be able to determine the acceleration. Hint: The pulley has no bearing on part b).
