Document Summary

Coef cient of static friction of a hard rubber of automobile tires on a street surface is 0. 90. What is the angle of inclination (of street surface relative to the horizontal) of the steepest street on which an automobile with such tires and locked wheels can rest without slipping. In order to keep a 1. 8 kg book from sliding down a wedge inclined at 30 , you press on it with a force of 6 n perpendicular to the surface of the wedge. The coef cient of static friction between the table and the book is. Three blocks of mass 2m, 2m, and m are connected by strings and pulled to the right with constant acceleration a. A 10 kg picture is held in place by two wires, one hanging at 50 to the left of vertical and the other at.
