Physics

A 2.0 kg block sits on a 4.0 kg block that is on a frictionlesstable. The coefficients of friction between the blocks are µs =0.80 and µk = 0.20.

(a) What is the maximum force F that can be applied to the 4.0kg block if the 2.0 kg block is not to slide?

______N

(b) If F is half this value, find the acceleration of eachblock.

______m/s2 (2.0 kg block)
______m/s2 (4.0 kg block)

--Find the magnitude of the force of friction acting on eachblock.

______N (2.0 kg block)

______N (4.0 kg block)

(c) If F is twice the value found in (a), find the accelerationof each block.

______m/s2 (2 kg block)

______m/s2 (4 kg block)
