A 1.9 kg block slides along a horizontal surface with a coefficient of kinetic friction μk = 0.30. The block has a speed v = 1.4 m/s when it strikes a massless spring head-on.

If the spring has force constant k = 120 N/m, how far is the spring compressed?

What minimum value of the coefficient of static friction, μS, will assure that the spring remains compressed at the maximum compressed position?

If μS is less than this, what is the speed of the block when it detaches from the decompressing spring? [Hint: Detachment occurs when the spring reaches its natural length (x=0).]

Explain why the detachment occurs when the spring reaches its natural length (x=0)

A mass of 5 kg is placed on a horizontal surface with a coefficient of kinetic friction of 0.4. A force is applied vertically downward to it and another force of 81 Newtons is applied at 14 degrees below the horizontal.
