A 1.9 kg block slides along a horizontal surface with acoefficient 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 thespring compressed?
What minimum value of the coefficient of static friction, μS,will assure that the spring remains compressed at the maximumcompressed position?
If μS is less than this, what is the speed of the block when itdetaches from the decompressing spring? [Hint: Detachmentoccurs when the spring reaches its natural length (x=0).]
Explain why the detachment occurs when the spring reaches itsnatural length (x=0)
