Q. An 8.30 kg stone at rest on a spring. The spring is compressed 11 cm by the stone. The stone is after that pushed down an additional 26.00 cm and free. To what highest height (in cm) does the stone rise from that position?
Q. To measure the static friction coefficient between a 2.2 kg block and a vertical wall, the setup shown in the Illustrating is used. A spring (spring constant = 410 N/m) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the block does not slip downward. If spring in such a setup is compressed by 0.051 m, what is the coefficient of static friction?
