    A Question about Frictional Forces

    Homework Statement A horizontal force of 15 N pushes a .50 kg book against a vertical wall. The book is initially at rest. If the coefficient of static friction= 0.6 and the coefficient of kinetic friction = 0.40, what is the acceleration of the book? Homework Equations F=ma static...

    Force on projected object at its highest point. What is the net force?

    Homework Statement A ball with a weight of 1.0 N is thrown at an angle of 30 degrees above the horizontal with an initial speed of 12 m/s. There is no air resistance acting on the ball. At its highest point, the net force on the ball is: A. 4.9 N, 30 degrees below horizontal B. zero C. 4.9 N...
