A 20 kg block sits on a 40 kg block that is on a

Give the answer for all parts of following problem:

Problem: A 2.0 kg block sits on a 4.0 kg block that is on a frictionless table. The coefficients of friction between the blocks are Âµs = 0.80 and Âµk = 0.20.

Part A: What is the maximum force F that can be applied to the 4.0 kg block if the 2.0 kg block is not to slide?

______N

Part B: If F is half this value, find the acceleration of each block.

______m/s² (2.0 kg block)

______m/s² (4.0 kg block)

Part C: Find the magnitude of the force of friction acting on each block.

______N (2.0 kg block)

______N (4.0 kg block)

Part D: If F is twice the value found in (A), find the acceleration of each block.

______m/s² (2 kg block)

______m/s² (4 kg block)

Please show me step by step and type in formulas used. I am so lost!!
