- A 0.46 kg block is hung from and stretches a spring that is attached to the ceiling. A second block is attached to the first one, and the amount that the spring stretches from its unstretched length triples. What is the mass of the second block?okp 9. To measure the static friction coefficient between a 1.25-kg block and a vertical wall, a spring (k = 790 N/m) is attached to the block, is pushed on the end in a direction perpendicular to the wall until the block does not slip downward (see figure). If the spring is compressed by 0.048 m, what is the coefficient of static friction? p136 skpl (p136 skp136 skp136 skp136 sko 136 skp136 skp136 so136 skp136 skp 36 sk1 36 sk skp136 skp136 skp136 skp136 skpl skp136 skp136 skp skp dreamstimemesi 9.

How much does the spring stretch?A block of mass ?=3.70 kgm=3.70 kg slides along a horizontal table with velocity ?0=4.00 m/sv0=4.00 m/s. At ?=0x=0, it hits a spring with spring constant ?=43.00 N/mk=43.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by ?=0.400μ=0.400. How far has the spring compressed by the time the block first momentarily comes to rest? Assume the positive direction is to the right.
