You press a rock of mass M against a spring of spring constant k compressing it a distance L. You release the spring and the rock slides on a table. You find that the speed of the rock is v, when it falls off the table after sliding a distance D. What is the coefficient of kinetic friction between the rock and table? O (kL² - Mv,?)/(2M|D) O (kD-Mg)/Mg O kD/Mg O (Mv,² -kL²)/(2M|D) O (kD2 - Mv1?)/(2M9L)
