Document Summary
Two identical boxes are being pulled across a horizontal floor at a constant velocity by a horizontal pulling force of 180 n that is applied to one of the boxes as the drawing shows. There is kinetic friction between each box and the floor. Find the tension in the rope between the boxes. Kinetic energy is a scalar quantity associated with the movement of an object. Assume that during very small displacement f= fcos is constant. Consider a block of mass m moving to the right under the action of a net force. There is a system boundary around the system. It does not necessarily correspond to a physical boundary. The boundary divides the system from the environment week 5 page 2 week 5 page 3. Calculate the work done by the spring force on the block as the block moves from xi = -xmax to xf= Consider a system that consists of a car and the earth.
